For pure PVE, I think the Pali, Druid, Shaman group is going to have an edge. Still catching my Druid up with the rest so I don't have much in the way of numbers to back it up, but I think it's the theorycraft winner. Still, Pali + Shamans is definitely strong, it's just not 100% optimal. As has been said previously, self rez, heals AND damage, etc. I went Orcs on my Shamans, just because what nuker doesn't want a built in, scaling ToEP ability? I do really want to play around with a DK alongside my Shamans now though, Thunderstorm + Death Grip could be interesting fun.
