Stasis does need new Supers and Strand. I made a forum topic about this a 3 or 4 days ago. I had a few ideas that could be "quick" to do. For Titan, make Diamond Lance a Super (basically it's like Hammer of Sol). For Hunter, turn Blade Barrage into Ice Shard Barrage. For Warlock, alter Nova Bomb: Vortex, instead of a vortex, when the Bomb lands, it freezes enemies and pulses freezing/shattering waves for it's duration. Or make a Stasis version of Chaos Reach. Not sure how hard it is to reskin these Supers, but a lot of the animations/framework are their for it. While completely new Supers would be nice, I would be cool with reskins to add variety to Stasis and Strand, if reskins are faster.

Definitely need other supers, yes.
