What do you think is the best 5 man team to go with for instance runs?
I have levelled a couple of solo toons, but wanted to get a little feedback before levelling a team.

I have a Pala or a DK tank I could go with.. thought about an all caster team, but once hc's are on the cards wouldn't they be a little squishy?

Whats the best healer atm? I can go with druid, Shammy or Priest.
