wizard should have cleric or bard as sub ^^
+1, totally agree with that.
However, if you're really into creating a wizard/warlock, then face the truth: you'll need loads of SP! I'd recommend getting the life drain stuffs, because they'll help you to survive. Also get some DoTs and the passives belonging to these skills. Don't get warlock nukes, because you'll have many of them from the wiz tree.
