I have a mixed 4man team of Paladin - Druid - Warlock - Hunter. Which isn't far from a better 3man I suppose I've been using this Paladin to boost the second group of 2xMage-Rogue-Priest, but you need gear to be able to boost properly in low lvl Dungeons. It certainly helps to have 2x lowbie mages helping with AoE there. How much would you like to "solo" at 60 though?
