Can't Warlocks AoE essentially as well as Mages and be more survivable while doing it?
A Mage who can blink/freeze/kite is great and all but most boxers can't realistically leverage that kind of play.
If you want to mitigate risk and/or have your cake and eat it also maybe try the following:
3Warlock+Priest+Paladin (with going in position as both as healers/buffers/cleansers).
3 characters AoEing and not losing any DPS due to push-back are closer to 4 AoEs with pushback than 75% (plus the Paladin can Consecrate if you want)...
Start Paladin as a Healer with better threat management and ret aura for pets when pet tanking & concentration aura when Warlocks AoE for no pushback... If you hit any content where pets can't tank and/or the Warlocks can't survive then upon spirit rezign switch the Paladin to his Tank gear and all problems are solved as you are now in the standard Trinity the game was designed around:
Tank+Healer+3DPS
Paladin+Priest+3Warlocks (or 2 Warlocks+Mage)
Note that swapping a Mage for one Warlock still gives you 2 Pet Tanks or an off-tank & a buff...
