I have only spent a day as a warlock and I can't tell much about it right now. HOwever, I love the spell effects and the first spell that I have can be very, very useful. ONe reason is because it can deal damage and remove any effects on the target that I aim it at. I can forsee that spell becoming very useful against magic wielders. Such as Darkpaw shaman putting on the wards and the spell we get at lvl 20 can remove the wards. very useful so I can imagine warlock becoming very powerful later.
