I took pally/shaman to outlands and it's been slowish. I blow past mobs, but geez that exp bar is going up slow (well, to me).

Biggest issue (and time waster) is figuring out what quests I can skip without losing a good quest opening up later. The other issue is just being tired of going through outlands.

I'm trying to stay in hellfire area until shammy is 62 (pally will be 63.5). Then it's off to Zang for kill quests only til 63. Terrok til 64. Negrand from 64-66 (or however far I can get). And then probably Blade's until 68 and I'm done.
