Thanks everyone. I decided to go along with a Druid together with a Priest. Priest as main, though atm im just playing my Druid melee (no downtime/ mana :P) and my Priest on follow with a couple of macro's to easily attack (VA, SW: P, MB, - Shoot). Druid Feral and Priest Shadow for now. Works awesome and I just reached 31 already (started a bit difficult to setup everything though, but once I had it running it went smooth).

I'm still wondering if I should stop at 60 and then go further solo and transfer the Druid to my main acc, or continue dualboxing. I think I will actually, solo playing is alot easier too, and I prefer my Priest above my Druid too (though Feral isnt bad at all). Kinda cool too, since I was pretty much doubting about which healer to take and get to 80, but the Druid healing came out really - really boring so far, while Priest healing is super awesome. No doubts now ^^
