I'd be interested in seeing more support for slower Warlock "damage over time" builds. Gargoyles could be a good fit, since they're the kind of sturdy, lumbering, pestilent creatures those more curse-oriented warlocks would probably use. Not sure about the balance of everything, but you get the idea.
