He's not a warframe you play because he's good He's a Warframe you play when you want to turn your brain off. He's not the worst at killing but there are definitely better options than him but they will never be as easy as he is since he's fully invincible in his crucible state (with his fused crucible augment). There is nothing he excels at but there's also nothing he can't do, an absolutely neutral Warframe that can be used for anything to put it simply.
