Completely useless post.. do some effort and do it yourself, it's so much beter than some animation on zhe webz.
Start a new rogue, walk to a mob, use 1 sinister strike and uce eviscerate... TADAA THE ANIMATION!!
log out, delete the rogue, go to a new race, repeat...
The only thing you would need to ask is for tauren and draenei animations, all the other classes can roll rogues.
If you want to see the 2H animations you can do the same, EVERY race has at least 1 class that starts with a 2H and uses an ability. Basically you can do this with warriors and use a heroic strike (also from level 1 and all warriors start with 2H these days), and for BEs you can roll a hunter and use a raptor strike..
And yes I know, for 2H you an also start ANY race in the game, but it takes longer to obtain a weapon and be able to use an ability with it.
