well, some people actually have fun through FL. It gives players with lesser raw skill (considering legit ones in this case) an opportunity to compete evenly with higher raw skill, non-FL players (although memorization itself is already a skill imo; only some people can actually do it in fewer tries than anyone else/do hardcore, non-repetitive stuffs. Take baka_baka_Koishi, for example. Regardless, it's not really raw, but still). Although I haven't tried it at all, I think it's NOT impossible to actually train your reflexes with FL, but then again it's much more tedious to train than with other mods, thus making people not go through it. Just my opinion.1.
I agree with XK2238 about FL stuff. It is possible to train your reflexes to play FL, i got better and better playing with it, BUT it is only readable at low bpm taiko maps and low SV/BPM converted ones. Also depends on the ammount of notes in the map, since the visibility area gets smaller when you reach 100 and 200 combo. Otherwise FLit is useless on taiko maps and imo should not count on them, cause memorization is not a competitive type of skill.. ANY player can memorize a map, it just depends on the ammount of attempts each one takes to do it. But there are players who can memorize easier than others and can't play hard patterns with good accuraccy or can't read high BPM on taiko maps.

This game is a rythim game ( meaning of course that you need to play in the right rythim), so accuracy should count way more than other mods, meaning that DT and HR should be more rewarded since it raises OD.Takes skill to play HD too, meaning you can follow the rythim, but anyway HR>HD. By the way, HR&HD IS playable.

I think converted maps SHOULD count as well, because there are songs you like, and there's not a taiko mode on it. But the converted ones shouldn't be weighted as much as taiko maps, UNLESS Tom94 comes up with a nice system.
