#1 - No I am not kidding about us having some warlocks that can solo stuff that a warrior and mage (?) couldn't duo. I am not talking about everything under the sun, just apparantly some MoBs out there somewhere. I am comfortable it is not a compotency issue, we were a top 50 (34 according to one site that was tracking EQ progress) serverwide guild in EQ; we know how to play the game.
#2 - I don't know too much about the PvP aspect of the warlock. We play on a PvE server so perhaps even the tactics employed by the warlocks in my guild may differ than those tactics on a PvP server. I really dont' know.
