I've noticed that the Hunter is the only class that somewhat has an indicator that allows enemy players to know if they're Supercharged. The Hunter would be the only class that would really need two indicators. As it stands players really have no idea if an enemy is Supercharged. That's going to be a huge problem once everyone has spent a good amount of time playing. It will add a random element to a lot of engagements which will dampen the competitiveness of the matches. By having an indicator players will have to make better use of being Supercharged which in turn will make it far more rewarding to use. I suggest having the player glow a soft color, not something that would make them get spotted easier but something to just indicate they're Supercharged.
