I did Vashj'ir on my pally solo, and just that was enough to deter me from taking my shammy team anywhere near it.

I leveled a lot in eots during it's CTA weekend. with full wrathful I absolutley dominated people in their cata greens. Easily 90% win ratio and quick 3 base cap games, 10 mins average.

Basically I did 80-82 hyjal, spent the next 2 levels bging and in deepholm. 84-85 some quests in twilight highlands and bging.
