Map icons that are too similar

This was posted in General Discussion a little while ago. But I think it should be brought to the attention of the devs - and it's not really a bug as it is a problem with the game interface.

When you are using the minimap, it is really hard to tell apart some of the icons (especially if you are colour blind):

• Red Kayn and Aatrox
• Urgot and Pyke (And there are others too but these are the worst offenders.)

Could we be allowed to increase the size of the map to give us more resolution on the icons? Or could the icons be changed a bit to make it easier to tell them apart?
