Using it wrong lol, I dare you to play someone like me using max discipline and vortex grenades. Go ahead, I dare to you place even one rift, then you can go ahead and tell me if the way you use them is the correct way. No amount of health is going to save you from a fusion either or even a sniper, a shotgun, a grenade launcher etc. you know why? Because by the time you even think about placing a rift I would already be on that -blam!- ready to emote and kill you.
