Thoughts:
NM: Generally okay choices.
Bird sprite: Straightforward map, the only tricky part is the end stream in which you might need some stamina and aim for it.
can't hide your love: AR9 200bpm, making it extremely dense and requires good AR9 reading. the OD9 makes it harder to gain accuracy on the map.
Deep Space: CS5, but overall straightforward map with some weird stream patterns (squares lmfao)
FUBUKI: Good choice for a modern map I guess, just a consistency test but be careful of the 1/3 jumps along the way.
Refuck!: I'm pretty sure Ex6TenZ chose this for the lulz. But nonetheless, 0still 5 mins, nothing special, consistency test also.
Onna to Onna: A map like Usatei, weird stream patterns, the middle part which is 210bpm requires some getting used to, and the final section with ridiculously fast sliders just like usatei.
HR: I'm liking all the HR brackets so far.
BSPower: This map was easier for me to read with AR10 imo, a lot of bursts.
Clock Strikes: Modern map so nothing really special, just very jumpy.
ODDS&ENDS: 5 mins HR also, consistency test.
HD: Arguably better than last round.
Quo Vadis: Very very tricky. 1/4 mixed in with 1/6 and weird rhythm patterns, but still a good song.
Blue Night: AR9 200bpm, extremely dense (I'd say harder than Awake), and as with most Renard songs, it's sometimes kinda hard to catch the beat (the pun lmao) so requires good hearing.
Reminisce: The least tricky map, yet the longest HD map. Real test of consistency.
DT: Difficulty step-up this time round.
Till It's Over: Literally Meikaruza. Alternates and spaced beats making it much harder, and it's of higher BPM than Meikaruza as well (This is 165x2 = 330bpm while Meikaruza is 300bpm).
Sai afure: Straightforward, but be careful not to be tricked by the intense music it's just 203bpm.
Niji no Asa ni: 225bpm, by far the highest bpm map in the mappool, but if you can do streams and bursts at this bpm then it's also the easiest out of the bracket.
TB: When you have kors k and RLC combined, the end product is always a read heavy map with a lot of tricky beats and alternates. This TB really rewards those who have good reading and finger control and consistency, unlike the previous rounds where one only needs to be consistent.
Nevertheless, great mappool pick as always, enjoyed myself to the maximum
