I managed to play quite a lot this weekend...
My hunter has hit 50! I finished off most of the available Hinterlands quests with a rogue friend from the guild. We each had a bunch of group quests we intended to pair up for, but then post-patch, many of them had the group label removed. We did them together anyway, and polished them off quite quickly. I've now wandered to Feralas where there are green quests galore, and I'm leveling up my leatherworking a bit. My friend and I will head into Zul'Farrak tonight.
I also played my mage a fair amount this weekend, and used up all the lovely double experience I'd accrued during her long rest. She completed Scarlet Monastery (with another frightening pug, but at this point, I think I'll spare you the tale), and most of Razorfen Downs. Still need to finish up the quests outside that instance.
My priest is 34ish, I think. Didn't play her much this weekend, but leveled up her tailoring such that she can now make stuff she can't wear yet. That's when I know it's time to slowly back away from the auction house... *cautiously steps back* No really, I had tons of silk on other characters, and together, they contributed toward the let's-move-on-to-mageweave-tailoring fund.
My paladin is at 20. Our paladin/shaman duo wreaked havoc on the harpies in the Barrens on Friday night. Steamrolled them! Bwahahaha, etc. We've yet to meet our match.
