I see it as situational. And for the purpose of discussion, I assume we're mostly talking about gun fire/grenade/melee as a means to combat......not super v. super. In more confined areas (e.g. rooms, hallways), Bladedancer can be hard to stop because of erratic movement. Sure, shotguns are great but landing shots can sometimes be tough. In these situations, a 1 for 1 trade my life for the super-cast life, is a big win if you can get it. Stormcaller can also be hard to stop at times in these situations, but for me 2nd to Bladedancer because they're more predictable. Out in the open for both of these though....just back pedal and shoot/grenade as they close distance. In somewhat more open areas, Sunbreakers can be hard to stop if you can't land head shots on them from mid-longer ranges and/or team shoot them. Golden Gun can be the same, and you're insta-erased if you miss. The nuke category goes to Nova Bomb and Fist of Havoc. Supers that erase you if you can't somehow get enough air or far enough around a corner.........which often times isn't even enough. Shadowshot is unique among supers.
