SSL is dead, the contrast with even a moderately populated realm is scary (I've been levelling some of my toons on Ghostlands) and frankly, the names are no better or worse than on Scarshield; in fact it's possible that SSL is worse, I've seen plenty of cringeworthy l33t names on there and because the population is so low, no-one bothers to report them. Blizzard don't really seem to give a damn about naming policies anyway.
I'm still undecided if I'll continue with WoW when MoP proper comes out, I'll give the new talents a try and see how it feels, but I would fully support a move away from SSL. If it's got to be RPPVP, then go to Defias Brotherhood.
