Is there any team combination that you just hated??

I didn't mind Shaman so much when we could put down totem sets.

Druids...There's just something about them. Although back in the day (pre follow nerf) 4x resto druids in pvp was awesome...

sorry to necro the thread, but I too find that mixed teams are boring to play. great to setup though.
Playing 5 of the same class is fun for me as its a bit like having a solo char whose abilities do 5 times the damage :)

That said: recently tried 5 druids and dropped them immediately.
