Yo, just as a response to
http://osu.ppy.sh/forum/p/2326175I took a look at your [All-Star] difficulty to see what all the fuzz was about.
To be completely honest, for the highest difficulty, it's rather boring to play.
A map doesn't need lol39484bpm deathstreams to be fun, but a lot of players find those types of things fun because they give a kind o thrill to playing. For anyone who can't play the highest difficulty of a map, they can instead play a lower difficulty. At least from what I see, you should try to make the most people
have fun while playing the mapset
as a whole. It doesn't help for the map to be accessible to a lot of players, if said players find the map boring. Instead, creating a good spread can achieve the same accessibility, just for your whole mapset instead, and gives you much more freedom to do different and interesting patterns for your highest difficulty.
Now to the map itself, here's the general impression I get from it: none.
What I mean by this is that, most of the good maps I play (even if they are just standard tv size maps or similar) leaves some kind of impression on me, either because of an interesting pattern, a hard part, a very intuitive part, distinct slidershape, symmetry that plays well etc. Right now, your map is very... Well, straightforward, and thus lacks that something to make a longstanding impression on the player.
Going deeper onto the patterns, there's a lack of variety. The stacks such as 00:26:052 (1,2,3,4) - could easily be moved around to create interesting movements for players. Moving the around also matches the change in pitch on each note, as the sensation of hitting something on the spot is more like repeating the sound. You also simplify the rhythm, such as at 00:23:769 - , which honestly doesn't play that well. Also mixing in sliders instead of always going with notes creates variety as well, even when the main rhythm stays the same. For example, the notes at 00:29:965 (7,8,9,10) - Feel more like long, held notes at (7) and (9), and as such, would still feel good even if you change them to sliders. These days, copy-paste is also considered fairly lazy and lacks creativity. You should probably remap the part at 01:58:824 - as well. Of course you'd like to keep a similar rhythm pattern to your previous "chorus", but a direct copy-paste of a section that doesn't make any real long-lasting impression makes the map boring. If you have a section that looks very great visually, and flows very well, then copy-pasting that for a similar section is fine, as that part was probably already considered fun by the player, and thus he/she would like to play it more.
You also seem to strictly stick with distance snap, which in itself is probably fine, though that again can lead to a lack of variety, and thus render your map "boring". If you are going to use one spacing, you might also want to consider 1.0x or similar, as the amount of movement you actually need to make on this map is, well, not a lot.
All in all, that's what I think is the general reason people think your map is "outdated" or whatever. Of course, you're free to disagree with the stuff I say here. But if you do decide to try what I've pointed out here, then be prepared to remap a lot. Your new map doesn't need to be a lol39484bpm deathstreams everywhere map, and can be just made more interesting even with the current basic rhythm. Just to take an example from your map that I think matches the current mapping trend, then 02:20:346 (1,2,1,2) - is very good, because of the clean, symmetrical nature. It also fits the section well as there are long sounds going around.
Also, I don't really think it will considering how you're trying to actually figure out this, but I'll say it anyway: don't be discouraged by what I or anyone else says really. In the end, it's all about how you want to make a map yourself that's important. There's not really a reason to map in a way you yourself don't enjoy. It still probably wouldn't hurt if you did try to match up to the current "mapping trend" though, with the heavy use of sliders, irregular spacing and/or pattern based mapping styles. I mean, at some point, you'd probably find a way to incorporate those elements into your current mapping style.
That's all I guess.
I actually do like to play oldstyle maps, so I don't have that much against this map at all. 
Edit: Oh I totally forgot, but if you want my opinion on anything, general questions to what I said or well, idk stuff that you can come up with, you could probably catch me in-game. Just ask me there about it. I do have exams like tomorrow till thursday though, so I probably won't have a lot of time until after that (I have no idea why I'm even here when I have an exam tomorrow but oh well).
well my suggestion in this diff is to follow the consistence rhythm more and add jumps, don't just follow the vocal
