warrior = charge, def stance, demoshout, thunderclap, shieldblock, revenge, sunder armor, sunder armor, shieldblock, shieldslam, revenge, tabbing the next mob, sunder armor, revenge, next mob, sunder armor, ...............

paladin =
Activate righteous fury, run into/pull as many mobs as you want, activate consecration and holy shield every 8 seconds, aoe all you want. auto-attack and seal of righteousness

so you don't need that much focus on tanking the mobs when you use a paladin. I'd prefer a paladin.
