Great thread! I can't figure out why anyone isn't mention the Q times... I haven't played in months and I got back on my Spriest and the random BG queues were awful. No skirmishes hardly either. I don't do much organized twink play, but I guess I'll have to start. Someone kindly suggested I turn off AV and maybe it helped (10 minute WSG q at peak time), but this is way worse and really the reason I got into this bracket in the first place.
OK BACK ON TOPIC: My spriest is a beast at least against random scrubs. I fought a few decent twinks, though, and I didn't feel threatened by any class other than maybe a solid ret pally or maybe ww monk. Healers I needed a little help from time to time to take down. The new priest stealth mode is godly. The devouring plague heal is godly. The orb glyph is godly. I don't miss pyschic scream because the stacking speed buff on my defiler's boots is godly. I really can't complain, I think we are in a great spot! I was top dps in almost all of the bgs I fought... won the few skirmishes I did easily. If I had some real competition in 2s or 3s I'm sure I would have some more realistic comments, but hey that's my thoughts so far.
As far as other classes:
Hunter is way less powerful than I remember and I'm glad. I have the feeling that you actually need skill now to play them.
Rogues are the same.
Ferals seem really strong, but not against me.
Disc Priests are obviously killer.
Ret pallies are pretty beast I think.
Monks got tha buffs apparently, but they aren't super scary just hard to kill and do actual damage.
Didn't see hardly any warriors, warlocks, shaman or mages that made any difference.
