[Suggestion] Establishing clarity in team fights.

Sometimes you're trying the focus the ADC or the assassin in teamfights, but if you're in a cramped area, for example in the jungle, it might be impossible to attack the enemy of your choice. The enemy team might be standing on top of each other, or a champion with a small hitbox (any squishy) might be hiding behind a champion with a giant hitbox (Sion, Mundo, Cho'Gath), making it impossible for you to focus them. Here is my suggestion: Similar to the targetable ally portraits on the left, add enemy portraits on the right (like the spectator mode). It looks like this in the spectator mode: http://i.imgur.com/d3cmawC.jpg
