How about some passive abilities in exchange for our supers. Eg 1. Get calus to make the hunters a cyborg grizzly or big cat to maul what ever you're targeting. 2. Have warlocks summon or conjure energy from the elemental plains that would take form of a shadow dealing ranged dps to targets. 3. The titans could get a mirror image of themselves whom would just headbutt the f.uck out of anything that moves. Also by sacrificing your super for these passive abilities, perhaps make a bar that when full it empowers your minions. Idk I'm throwing it out there, bungie talking about steering towards an mmo style game, this is the kind of sh.it i would want in a mmo style shooter.
