I really liked tai chi with about 360 frames so people dont have to wait others flying around like shaolin monks. It just combines the best parts of wushu and normal so you can do nice acrobatic stuff like in wushu, but also most of the matches are nice, unlike in wushu where maybe 1/5 matches have something happening. Classic would also be ok as its bit of a mix of judo and tk and because of the close distance its quite imposible to make boring "both kick and bounce back" matches.
Maybe classic coz i kinda mis that mode now that theres only 1 classic server and its always full
Classic is also kinda skill requiring coz you cant really win by having a good copied starter like sometimes in tk. And i really dislike all modes that make winning mostly defined by dq, its just so much more boring than smashing your opponent to pieces.
