Yep, my thoughts exactly. I did the same thing when WOTLK came out, and also BC. When the patch before TBC came out, certain mobs around where Karazhan was going to be put were level 60 something, took like 8 people to take them down. But we did, and they'd drop Netherweave Cloth. I sold a bunch on the AH for hundreds of gold, which was a lot back then.
It was pretty fun.
I got extremely lucky with green weapon drops at TBC launch, so all of those people who were coming through at 58 - 60 without top end raid gear were buying them for insane amounts of gold (at the time) was getting about 70 - 100g for weapons with the good stats e.g: of the bandit etc.
70g is pretty much nothing now, but when I was leveling my way to 70 it was great
also, Beta servers have gone down, hopefully the new build is being deployed. This patch seems to be the start of the number balancing which is always good to see. Arms' mastery is getting an extra 25% weapon damage stuck onto it, and they might as well just delete the Ret tree for paladins. It has become so RNG based in Blizzard's attempt to give Ret something to do other than hit buttons as they come off cooldown that you can go for a whole fight without seeing a single Hand of Light or Divine Purpose proc.
Makes me sad, used to love my paladin
edit: Wow, Balance Druids sure have got a lot this patch. Might give one a try if I can get a premade character over.
