An intense teamfight, where 10 players, each with different objectives, which change every second.
Mind blowing speed and efficiency.
To me this looks beautiful, and i personally would like to consider it as art;
5 controlled characters going at each other's throats for blood and glory, bringing out the best in them.
As such any individual cannot produce this type of art alone; they will have to be at top form, be of equal skill and complete focus.
People having to mechanically outplay, adjust and re-evaluate every second in a graphic presentation
