Something that could make map awareness a little easier
I think that icons on the minimap could change hue and/or value based on the health of the champion they represent. For example, an enemy at 100% would have a light orange border while one at 10% health would have a dark red border. This would make it easier for teamates to know when to help without losing precious attention looking at their lane. For example, if I'm the top laner and my teleport is up, I could easily see that both the ally and enemy ADC are low, so it would be best for me to TP in to put the fight in our favor. Things like this would just streamline the game and make voice coms a little less OP.
