I'm sure all of us have had times where you pop around a corner to kill someone and then just as you are about to finish them off they press the magic buttons and you're suddenly dead and they're dancing on your corpse. While the concept of supers is all well and good I think bungie needs to implement a warning system/indicator so you know when someone's super is fully charged and can stay out of their way. I'm not sure how this would work, maybe a gold glow around the character or an indicator next to their name but it would just make supers a little bit more tactical and not just "There's an enemy! RB+LB!"
