I think this would be a useful feature especially for new/casual players.
Basically, sometimes it would be very helpful to see the name of the champion on an enemy or ally instead of a summoner name to quickly indentify him. There are too many champions and it is getting hard to keep track of how everyone looks.
This problem is much bigger also thanks to skins, it makes it even harder to identify the champion as fast as possible.
In a game against bots, you can see the champion names immediately, and thats helpful.
There could be a feature in options "Replace summoner names with champion names".
I would like an answer or a thought from Riot employee if possible.
