I mean its pretty obvious that Blade Barrage and Nova Warp are the supers everyone is most likely using if the symbol shows a Golden Gun or Nova Bomb Icon. But it would be a nice touch to show just what supers are being used by the enemy team when you pull up your ghost, so you dont have to guess if its Fist of Havoc or Thundercrash, or wait until you engage the enemy to show what abilities they use.
