I have been working on an Alliance team now (novel for me, I always play Horde) and went PaPMML and I have to agree, I will always have one. The Warlock brings so much to the table. I exclusively am using the imp. I am specced full destruction right now so the mana is not as bad and I tap on the run with renews from the Priest to help keep up the pace. The Paladin has fire shield, retribution aura, blessing of sanctuary and a shield spike. He is a total reflect machine! I have a castsequence rotation that if the fight goes a little long he casts drain soul to keep the shards up so I always have health and soul stones. Curse of the Elements really helps the mage's damage as well. The best part though: Staying at dungeons for ever, sending the mages back to sell and then just summoning them back
