I realize this may be difficult to code for the A.I. but I thought I'd at least give it a shot. I'm thinking of a flying specimen to replace the Patriarch. The specimen would have no ranged weapons but would swoop in and maul the player, if the player has low enough health, the specimen will grab them, fly off, and eat them alive.
I'm thinking it should resemble a cross between a spider and the flying Deadite from Army of Darkness (You know the one that abducts the girl and brings her to Evil Ash).
One thing that would add a lot to the specimen would be how it summoned other specimens. I think it should have two ways of doing so: A howl that summons a bunch of them. Or, when it has successfully killed a player, it should take his body, eat it, and then puke out a MASSIVE horde of enhanced Crawlers (they are slightly faster and take more damage).
