The PTR exists! And it uses talents and such a little older than in the WotLK beta.
Myself, I copied over my 70 mage, 70 warlock, and 70 hunter. Spent most of the time today on the hunter, to experience the hilariousness of the pre-nerf survival tree.
I'm talking, a 70 hunter in levelling greens, a couple of BoE blues, and engineering goggles. This is not what you would call good gear. Or even passable gear. I walked up to a 70 elite a few minutes after logging on, threw down an immolation trap, hit him with serpent sting, kited him over the trap, sicced my pet, threw the requisite Lock and Load Exploding Shots and... well the plan was to feign death and continue DPS but he was already dead. So instead of falling over to feign death I bent over to loot. Wooo, fun.
