Outside of some niche situations (arc burn/solar burn) voidwalker is the best class hands down. Infinite scatter grenades that regen health. High damage large aoe super that regenerates itself quickly through obsidian mind. In pve you don't even need to fire your guns if you use voidwalker correctly. In pvp, you get blink your choice of axion bolt or scatter nades which are both good. The ram or voidfang vestments, and an excellent counter super.
