So the consensus is that, in fact, Drahzar does not suck eggs, but needs to be pointed and clicked at a unit all by his lonesome? I'm thinking of running him with an Archon with a WWP and half Venom spam. Archon goes up, drops the pie plate and out pops Drahzar and company (along with a Talos and a Cronos), who then go forth and do their thing.
Drahzar going solo adds an new twist to things, I just hope that this tactic doesn't end up all "Yoko" with a solo IC.
We shall see, but it's all speculation at this point as I don't even have a model for the Incubi Poobah yet...
