There's different kinds of players in Wushu.
There's the people that want to win above all and the players that want to have fun above all.
Players that put winning above everything will mostly use an aggressive move to open with and deal damage, maybe luck out a bit, and not comeback or even tripod.
This is very annoying to the players that play for fun.
Players that put fun above everything are mostly the more experienced players, they will not use pre-made moves or "freestyle". Most of the time they will move away the first move and comeback after, rendering the premade aggressive move useless.
I love to play like this because I like the freedom in Wushu.
From what I've read, the people are angry because they have no answer to your (arguably boring) playstyle, which is okay. They shouldn't flame, they should just move out of the way (if they think they are better than you and can't stand losing to you) or just look for people that share their playstyle.
That said, I do advise you to try freestyling as well, you will get to know your Tori a lot more and ultimately become a better player in general.
Sincerely,
Alpha.
