Honestly, we should have the option to turn skins off
As more and more and more champions, skins, and indicators get added to the game, it gets harder to tell them apart. Being able to turn skins off would certainly help with mid-fight readability. And, if you didn't want to go that far so as to make your skin purchases pointless, you can have an Allied skins option and an enemy skins option. (I mean, you don't need an option for yourself because you can always just go classic)
