Two more thoughts I've had since taking my premade hunter to Mt. Hyjal;
1. The mobs spawn WAY too fast. Yes, they're extremely easy to kill but it took me 30 minutes to do what should've been a ten minute quest because mobs respawn almost immediately.
2. Minor thing here, but it makes me sad
. The green quest rewards are already better than the T10 gear you start out with (for the most part). I'd like to get just a little more use out of the full set of T10 before I start replacing it with greens, since I'll probably never be that well geared once Cata goes live.
