When I was writing this column on warrior attacks, I noticed that a lot of players who don't play warriors came in to comment on their animations. I specifically noticed druids (especially feral/guardian druids), and rogues commenting. This got me to thinking if part of the problem is that the monk class really exposed a vulnerability. It's easier to see that your character model isn't keeping up with new racial choices like the goblins, worgen and pandaren - you can just see one standing next to you in Org/SW or a raid/dungeon/scenario. But to notice that your animations aren't keeping up with the new hotness, you have to see the new hotness. And it can be hard to notice what someone's attacks are like when you're focusing on your own.
Now, of course, the argument could be made that WoW's animations are pretty good. Making a change simply for change's sake would be a diversion of resources. But it seems to me that, with all the talk about updating character models, there's at least some room to discuss updating our attacks as well. Most classes use the chosen race's special attacks (you can see what they are by using a model viewer program, or Wowhead's model viewer) with specific ones like Dragon Stomp, Special1h, Special2h, and so on.
