I currently have 4 shaman and either a pally or a dk as a tank for heroics. I have no problem using either but I miss the sp dmg debuff when I use my pally. So I just started leveling up a druid (currently at 39) to replace one shaman when using my paladin as my tank.

But reading this, I may be better off keeping my DK as the tank and replacing one shammy with a mage...

I'm looking to have the best possible team from my toons to farm heroics like mad in 3.2. decisions decisions...
