Quest to 60 imo. It is still very very fast, all your chars will have equal gear and more money, your defense rating won't suck as much, you will get much needed practice instead of just twiddling your thumbs, you only have to add new macros every once in a while, instead of a heap all at 60.

Also, make a macro for all your shammies to target self /cast lesser healing wave, nice way to heal everyone to top off party wide dmg.
