Personally, I'm enjoying this expansion. I got my five shammies to 85 last week, now I'm leveling my PvE team. They're 82 at the moment, so I have a bit to go. I'm enjoying the quest lines. I also really love being back in Thunder Bluff as my home.

My focus on this expansion is PvE. I think the shammies will get a few battles in, but I'm going to actively try heroics on this one with my PvE team. That, and making gold. I've never had more than 40k gold, and after going into the expansion with basically 0 gold, I have 58k even after power leveling all my alchemists and powerleveling my pally's enchanting and blacksmithing.

I'm making a major change in job/location, so I may be taking a vacation from WoW soon whether I want to or not. But until then, I'm enjoying the expansion.
