While my 5 shammies are always going to be my favorite (especially with the new toys we got) I'm also going to love my 5 mages methinks. The main (my first 60 in vanilla) is 80, and the slaves are currently resting at 66. Got them all specced and glyphed this morning and started playing around on dummies, and I think a 5 frost mage team is going to wreak havoc in open/bg PvP. Shammies have 20 totems, frost mages have 5 water eles, 15 mirror images, and that new ring of frost thingy. When I popped my eles and mirror images I looked like a raid

My priest/locks I haven't decided yet. I haven't even specced/glyphed them yet because I haven't really been impressed with the new soul shard system. I'm sure I'll figure it out later though.
