I'm suprised that no one mentioned Mage/Shaman in any serious light. Both classes have pets (to keep mobs at a happy distance), but a mage pet is completely capable of tanking, and tanking WELL. Add Champion or Panther (or ~drool~ shammy 2.0 click) to the mix, you now have essentially 2 melees proccing the Shams procs and 2 casters doing insane damage. Plus the shammy heals are just PERFECT for mage pets, plus slows. If you do a troll shammy, and get the snare click... well even better.
And the best part? You don't have to really run 2 toons all over Norrath. Mage: Call of the Hero incoming to MR. SHAMMY you will not evade me!.
Plus pet toys, utility summoned clicks (shammy invis sucks), summoned focus effect jewelry, the BADDEST pet in game, and SICK damage shields.
And you can make Necros and Druids cry little tiny tears of woe: You can kill mobs that summon. At will.
I would SERIOUSLY look into this combo.
