Thanks a lot for the fast and very precise answer :-)

I think i'll keep the druid for now and try the approximation. I kinda like have a (almost) fully buffed team, and as you say i'm already used to the druid. As for setup i have a singe nuke button - and i'll like to keep it that way (it has some modifiers for special occasions). None of my dps'ers has ANY logic in their casts - they just spam lightningbolt/frostbolt/wrath, so there's room for improvement when I hit 80. Also the mage might end up with arcane dualspec so I can try that out.

Next step is to set up something for jousting and do argent tournament dailies until 80.
