I got a SoR and thinking of making a feral or a rogue. And i will continue playing so i'm looking forward to MoP and all i care about is PvP and some casual raiding. Rogues look more fun but looking into beta footage and their talents, rogues seem nerfed to hell ( 2 base abilities in the same tier wtf blizz ) while ferals are getting some new toys. I will also be doing alot of Wpvp.
Right now I'd call it a toss up, but heading into the expansion it looks like rogues are getting nerfed, as you said, while ferals are getting sort of nerfed and buffed. I think the buffs outweigh the nerfs, but many seem to disagree. Either way though, at this point I would recommend feral, simply because you can always count on at least one of the specs being really good.
