It would be cool for if the bots had a random skin. This would allow players to see what the skin looks like in game and it would just make the game better overall. What do you guys think?

I see your point. It sounds cool but there is a problem:

Starters would get confused about who they are playing against, since they already know very little about champions, they now would have to recognize each one's skin.

I know it sounds silly since the champion's name is still above their HP, but if you were new it's much more probable that you remember about a champion based on how he looks like than his name.

This was released ages ago for intermediate bots. Lol.
