Thanks Fur.

I did mention that I've done Western Plaguelands. Netted me probably a level and a half.

I've avoided Un'Goro, but I probably should hit it.

Burning Steppes is a zone I'm not that familiar with, but scanning Wowhead's quest database shows a very limited amount of quests. (I'm horde and it looks like there is a disproportionate amount of quests there for alliance).

Already have done Searing Gorge too.

Instance quests I hadn't thought of. When I leveled my main I was catching up with friends who were already 70 so I skipped almost all the old world instances other than Scholo. I'll have to look into that one. Great idea. Thanks!
