DoubleTime Average: 5.51
Hidden Average: 4.96
TieBreaker Difficulty: 5.49
Mappool Average: 5.33
Here are some maps that I think are quite tricky or hard:
- Studio EIM - Crescent Moon Island Boss Theme ([ -Scarlet- ]'s Extra) by [ -Scarlet- ] Difficulty 5.57 NoMod
A noob Malaysian mapper. CS5 map. This map has pretty tricky stream pattern, small circles also increase the difficulty aiming those repetitive jumps. - Kano - Six trillion years and overnight story (OverNight) by StarForYou Difficulty 5.66 NoMod
A very tricky map, has a lot of kick sliders, if you are not paying attention you might miss all the notes there. A VERY NICE MAP IN 2015 PLEASE VOTE THIS KAPPA - Hito Ookami - Decisive Battle! Ho-Oh! (Lvl 100) by [Takuya] Difficulty 4.85 HardRock
First CS6.5 in this tourney, just be an aim expert and you can easily fc this. Two very tricky 1/3 space stream. Be careful there is a part that kills your HP, if you don’t have full HP when you reach that part, you might fail the map (but this doesn’t matter because you have enough time to revive). - Star Driver - 5 Centimeters Per Second (Right Back) by Come[Back]Home Difficulty 5.54 DoubleTime
First AR10 (AR8.5 DT) DoubleTime map. Not very hard actually, you got speed, you can play, pretty simple. - Rise Against - The Eco-Terrorist In Me (Expert) by BOUYAAA Difficulty 5.14 Hidden
Tricky map, all the alternating patterns, can easily break combo. - DJ SHARPNEL - FAKE PROMISE (TRUE) by Urushi38 Difficulty 5.49 Tiebreaker
Very straightforward map, some part you have to burst, overall very jumpy map. A deathstream at the end of the map, possible to see a fail there?
I guess goreshit - o'er the flood (The Flood Beneath) HD pick and Hito Ookami - Decisive Battle! Ho-Oh! (Lvl 100) HR pick will be the most banned maps.
AKINO with bless4 - EXTRA MAGIC HOUR (Extra) NM pick and Kano - Six trillion years and overnight story (OverNight) NM pick will be the most played maps.

DoubleTime Average: 5.07

NoMod Average: 5.24
HardRock Average: 5.19
DoubleTime Average: 5.07
Hidden Average: 4.88
TieBreaker Difficulty: 5.10
Mappool Average: 5.10
Here are some maps that I think are quite tricky or hard:
- Kola Kid - can't hide your love (Can't) by Kert Difficulty 5.05 NoMod
This map has a lot of hidden repeat sliders which stack behind another repeat sliders, makes this map a lot harder to play. - Shiena Nishizawa - FUBUKI (Blizzard) by Rizia Difficulty 5.29 NoMod
The trickiest part is at the chorus, which you might have to alternate or single tap the 1/6 spacing notes. We might see a lot of players break here. - ryo (supercell) - ODDS&ENDS (Insane) by Colin Hou Difficulty 5.02 HardRock
Another 5min HardRock map, this map has a lot of hidden jump notes and you might easily misread it. There is a very calm and slow part where all the notes are NC so you can’t see where the next note will appear and easily fail the map because of low accuracy. - Tristam - Till it's Over (BD's Hard) by [Luanny] Difficulty 4.90 DoubleTime
Alternating DoubleTime map. You have to alternate the whole map because the song bpm is very high unless you are very confident with you single tap speed. The slider tick 2 also makes the map easier to break. - M2U - Quo Vadis (Extreme) by buhei Difficulty 4.65 Hidden
Difficulty 4.65, but probably the hardest map from the mappool. This map has a lot of 1/6 stream and with the Hidden mod on, you hardly recognize which one is 1/6 stream and which one is 1/4 stream. Only player very confident with his reading skill might choose this map. Extremely tricky map. - kors k - Playing With Fire (Sota Fujimori Remix) (420) by RLC Difficulty 5.10 Tiebreaker
This is an interesting map. Unlike the previous tiebreaker, this one is totally different style of map. Duplet everywhere, and some patterns are kinda tricky.
I guess M2U - Quo Vadis (Extreme) HD pick and Memme - BSPower Explosion (Another) HR pick will be the most banned maps. The first one is extremely tricky and the second is very easy to fail and really hard to revive.
syatten remixed celas - Bird Sprite -Awakening of Light- (Another) NM pick and ChouCho - Niji no Asa ni (Insane) DT pick will be the most played maps. Both of them are very straightforward without any tricky pattern.

NoMod Average: 5.04
HardRock Average: 4.80
DoubleTime Average: 5.13
Hidden Average: 4.79
TieBreaker Difficulty: 5.26
Mappool Average: 5.00
Here are some maps that i think are quite tricky or hard:
- mafumafu - Yuugure Semi Nikki (Yuugure) by L_P Difficulty 5.11 NoMod
Malaysian mapper. This map contains a lot of hidden spaced triplet at the chorus part, you can easily get caught and miss. I barely believe people can FC this map in the tournament. - TOTTO - Onigami (Expert) by Kloyd Difficulty 4.70 NoMod
This map is totally underrated. CS5 making this map harder to aim. I can’t say this map is harder than other map in the NoMod bracket but I guess player will easily random break on this map. - EGOIST - The Everlasting Guilty Crown (Heart) by captin1 Difficulty 4.63 HardRock
This map is easy. YES EASY! But because of the song length, it turns out to be the trickiest one. Low BPM and long song length in HR actually quite challenging for newbie HR players. - KOKIA - Ningen tte Sonna Mono ne (Humanity) by Lizsig Difficulty 5.07 DoubleTime
CS5 DT. You can either choose to alternate or single tap the whole map. The challenging part is at the chorus, where you have to single tap or alternate 8 notes in a row. - kzlivetune ft. yanaginagi - empty (Insane) by Xivaxi Difficulty 4.91 Hidden
Well this map is so calm, but the mapper try to make the rhythm trickier. Listen carefully to the music and follow the rhythm. The last part of the map is the hardest, so I guess this will be the most banned map for this round. - FELT - Puppet in the Dark (Out Of Place ARTifactS) by Mackenzie Difficulty 5.26 Tiebreaker
Surprisingly this map is actually easier than every map in NoMod bracket in my opinion. Just be consistent and win the game
Well the mappool has more variation now, two CS5 maps (not included HR), high slider velocity map and duplet map.
I guess kzlivetune ft. yanaginagi - empty (Insane) HD pick and EGOIST - The Everlasting Guilty Crown (Heart) HR pick will be the most banned maps. One you need to have good eyes and ears to play, one you need to have good consistency.
Reol - Asymmetry (Guycat's Extra) NM pick and u's - Snow halation (TV Size) (Insane) HD pick will be the most played maps. The first one is pretty straightforward map like strangeatractor map last mappool, which turns out to be one of the popular pick map. The second one is very easy in Hidden bracket, so probably this map will be one of the strategy pick against non-HD players since they will probably ban the other 2 HD maps.

Here are some maps that i think are quite tricky or hard:
- kors k - Insane Techniques (Azer's Extra) by Azer Difficulty 4.57 NoMod
This map is extremely tricky at the end, you have to be able to consistently play spaced streams and also jumps, or else you will easily miss or slider break. Alternating is needed in this map unless you are speedy enough to single tap without missing the sliders. - Seiryu - Ultramarine (Another) by RLC Difficulty 4.92 NoMod
RLC's map, as always very straightforward map, but a lot of patterns can make you easily misread and miss. - sana - Kokuhaku Yokou Renshuu (Milan-'s Insane) by Milan- Difficulty 4.51 HardRock
This map isn't the hardest map in HR pool, but the spaced streams and sudden jumps are quite tricky for getting good accuracy. - Train - 50 Ways to Say Goodbye (Insane) by mancusojuanmattos Difficulty 5.13 DoubleTime
Probably the hardest map in the current mappool. This map is extremely fast, and very jumpy, a very nice choice for speed players. - Yousei Teikoku - Torikago (yami) by Furawa Difficulty 4.28 Hidden
Oh no, Hidden in this kind of map. Please increase your game volume so that you will be able to hear the rhythm accurately. Beware of the SV changes, they might confuse you especially in Hidden. AND THIS MAP IS OD8!!!!! - Shimotsuki Haruka - Re:Call (Re:Call) by -Nanaka- Difficulty 5.06 Tiebreaker
To be honest, this map is too easy for Tiebreaker. At the beginning of the map, it was too easy and I started to worry about the later part because this map's difficulty is kinda high. As expected, at the last part, the map became harder and you have to be very consistent to hit all the jumps. I think that part will determine who the winner is and maybe a comeback will also be possible.
Overall there is a lot of variety in this mappool. Alternating, streams, jumps, rhythmic.
I guess Yousei Teikoku - Torikago (yami) HD pick and kors k - Insane Techniques (Azer's Extra) NM pick will be the most banned maps because these 2 maps are very tricky compared to other maps.
senya - Hitorishizuka (Satellite) DT pick and Zektbach - L'avide (Another) HR pick will be the most played maps. These 2 maps are pretty easy and there is a high chance we will see an accuracy fight.
Good luck to all the players!!!
