I'm not sure if this has been posted before (I'm quite new to the forums) but I have a suggestion.

When an enemy goes to use a spell or attack on you, they glow orange.

What I suggest, is that if an ally (for example, Kayle) is trying to cast a support spell (her heal or Intervention), they should glow blue (originally, I thought green but that is taken by selecting the unit already).

So, what do you reckon?

Agreed. I can virtually never heal my "OH****IMGONNADIE" teammate who's running backwards for about 1/2 his/her health as nidalee because they run faster than me. ALWAYS.
