WotLK Melee Attacking Animation Bug

[Sonatherniuss]

Hello. I am experiencing some very disturbing visual problem while playing this game. My character model often freezes at the middle of a weapon swing animation or sometimes it ignores the attacking animation all together while i am melee attacking my target. The thing is that this visual bug only does appear on the warmane servers. I have changed my realmlist to play on the other wotlk servers which does use the same client (and i have tried many) and it never happened once on those realms. Can you help me with this problem? Thanks.

I have uploaded a video on youtube to show you whats happening exactly.
