Wow. Thank you - some very good tips. (btw. I took your ref link for IS ;-))

I won't take a warlock with me, I've got one on lvl 56/57 and if I change my mind I'll just take him there. But I really don't like them to play.
I can't really see the advantage in taking a boomkin with me. It's just a second druid I'll take with me and I never played this class and can't really play it.

IF I would change one shaman out, I'd take a mage (water,food,int buff,sheep,dmg).

Your opinion?
