On topic: Even if you can't cthulhu headed lion because your dm doesn't like epic things, nabs alone is the reason why so many builds dip in binder, like hellfire warlock. The binder also has a lot more versatility as a class, with the ability to be build as an amazing scout, one of the best non-spell grappler, easily specced party face, tank, weapon finesser, or blaster that can do comparable, if not exceeding, damage to a low-mid op warlock (at high op, all bets are off (although anima mage))
