So i just started playing wotlk on this server, downloaded the client from warmane website (not the HD version , its the original version), and happily created my human male warrior on icecrown, but then i noticed that my war's melee attacks' animations were missing while i was dancing around my target , i can only see dmg numbers, but with no animation. but when i stand still, i can see the animation. I also tried human female pally, DK, they seemed to have the same problems.
is it just me that having this problem? or something went wrong ...I really need some help or advise here.

thank you
