Grab detonation+backdraft for sure.Demonic heart of Chatha for the regens.Overloaded shockblast really plows through aoe pulls until you have 5 points in ring of fire and then it is still good.Grab soul resonance and blazing fire for quick debuffing along rapid recharge for shock and combustion for hellfire stream.And all the way to pact of earth walking for your pet to deal some decent dmg and trigger a green heal for you.1 point in wicked bolt and 1-2 in possession for more ccs.
Basically any pvp hybrid going down to poew posted in this thread will do fine in solo pve.
But you can probably take any build you want and have an easy way though all solo pve content unless you are doing lvl 80 khitai stuff in lvl 50 green gear :P.
