To me it doesn't look like the Boar animation is all that much improved. All I can see when I look at it is the shoulder armor twitching out like a bad ragdoll that's about to launch off into space.
And why retouch the crappy boars but no love for the talbuks, who have many obvious problems? And would probably be more enjoyed by players for nostalgia reasons, since they harken back to the TBC talbuks.
