Well, they still are the best support class, they have an OK burst, not the best, but okay, offheals can crit nicely, they are viable for arenas with some comps like ret/rogue, or ret/hunt or ret/fire mage and you can easily go 2k+ if you know how to play, BGs, I have no prob to be in the top 3 dmg done with my 522 ret. So all in all, is it viable, yes it is, will you be some1s first choice for arenas or RBGs, or even PVE, probably not, unless youre really that good. I wouldnt suggest rolling it unless you really love to play it, there are better specs to roll and do better on them with 50% less effort, but you cant say that they aren't viable.
