everyone says he has all the tools he needs to compete, or that the variations do what they're "meant to do," but i think looking at it in a vacuum like that is a bit silly.
if you compare his toolset to the other top half of the cast, why would you pick quan over them? is it not true most offer the exact same offensive potential, with a stronger/safer/less meter-dependent neutral/pressure/frame trap game, while generally having far better defensive options?
what tools do quan have that others do not have access to or easy ways to circumvent? the only *real* strength he has over others is zoning, but zoning in this game is generally pretty inconsistent.
and lastly, it shocks me how many of you are fine with sky drop being a useless move by saying "oh, that's what warlock's for." no, in any possible consideration of game design, that is not an acceptable justification for a useless move. if it wasn't intended to have some sort of application, it shouldn't be in the game, but as it currently stands it doesn't really have any practical uses at all. (you give chars 'bad reversals' by giving them long recovery, no comboability, not being cancellable etc. not by outright the move being too bad to ever consider seeing use.)
