Just idle wondering. Are there team-color reliant triggers or something? I figure in something like DotA it's just so you don't get confused about which colors are on your team or something like that, and so you can immediately recognize that that Omniknight IS in fact an enemy and about to kill you.
But what about on something like Sunken City that, for the most part uses assets that don't really look at all similar to any of the heroes?
