Granted I haven't played the beta so I don't know the zone's overall story but I think given the fact that revendreth is in a dire haves-and-have-nots type of situation (an afterlife having capitalist classes is totally bizarre to me but w/e), it's very obvious we're going to see an uprising by the "poor" citizens of revendreth against the elite who are hoarding all the anima.
It seems likely to me that Garrosh will likely break out (or be broken out) and lead (or at least greatly assist) the uprising against his torturers, finding his own sort of redemption that way. What do you think?
