Warlock is more of a zoner so I don't think he needs any more combo potential. Corpse drop is more than good enough too. It's an overhead-low, very good damage and I don't think anyone can reflect/parry/absorb it, not even Jade. Maybe Terminator but he doesn't get anything from it except avoiding the chip damage. And his recovery from that move is slow af. And characters without a front flip jump in can't even do a jump in to avoid the low and get a bit closer because the low hits them out.
