They could halve silly FPS resources since only flies can tell the difference between 22FPS and 60FPS (they have many eyes) and save those resources for better things. Other fighters online would flash yellow when you could hit them with supers, red with normal attacks to build with supers, and when you turn green stay away because you take 2x the damage. Also make it 3D with no lock-on to increase learning curve so only hardcore players fit in.
