I feel like Blizzard really went hardcore about not giving monks anything that might make them desirable from a composition perspective, hence we got stats buff that already popular classes bring and we get crit from windwalker which is also readily available. It's the same when you look at the absence of solid raid utility in any of our specs too. Blizzard was very careful about not making another deathknight scenario. I imagine by the end of the expansion we might see something cool come our way, remember shaman didn't have spirit link totem at the start of cataclysm so it's possible for quite radical and powerful abilities to be introduced mid expansion. I'm expecting ultimately that some other class is going to get another copy of heroism/bloodlust some point soon, most likely a hybrid since right now it's still a little awkward for a 10 man to bring all the buffs whereas 25 man can basically bring whatever they like now and be sure they end up with everything somehow.
