First if they went in with the intent and the team composition and gear layout to enable infinite supers in the first place it is highly doubtful they would panic super at spawn to save themselves (they could just take the death and respawn closer to simply their teammates). Second, in order to keep them separated you'd have to have incredible control over the spawn points while also managing where the enemy team is and fight both away the same time. All they have to do is group up again and let it roll. The difference in skill that takes is enormous, and if they screw up, no problem try again. If lone ranger makes a mistake there goes the game. There is a chance for this method to be stopped, but it would be an uphill battle the whole way and there's no guarantee they couldn't just get right back into it.
