I currently have 5x druids and 5x hunters at the cap on both alliance and horde side, so I will level the druids first and gather, gather, gather my brains out to make lots of gold while I level, then do the hunters.

Druids will let me do random dungeons - 1x guardian, 3x balance, 1x resto, and the hunters will just be super fun to play.

This will also let me swap in hunters for the balance boomkins if balance isn't easy to box this go round - I think my hunters would use spirit pets to aid in healing.
