Are people having a hard time with this character or something? I just don't see too many people using Kula anymore and I haven't seen or found anything new with her in the console version. It's kinda saddening, since I'm actually a loyal Kula player.
Kula has some anti-air weaknesses. Her DP is awful and if it hits a crouched player she can be punished by a full combo. Her down C is -17 on block/whiff so it's also full combo punishable. That leaves stand A and stand B as her quickest/safest anti-airs, which aren't going to cut it vs air CDs and the like. I feel Counter Shell isn't as powerful as 2002 either, it seems to have a smaller hitbox and fewer active frames. Not as good vs air as I remember, but that might just be my perception. Her ability to control space is also drastically reduced from 2002.
That said, lots of characters have poor anti-air options and can still do just fine. She has great hitconfirms, corner to corner combos, a decent damage to meter spent ratio and the absolute best anti-projectile skills in the game. I think King is going to become more popular so having some skill with Kula might come in handy.
