Summoner Icon Description
I didn't really find a proper Board for this, so I'm going to use the Story & Art board (because it kinda contains/targets art). Please forgive me.
My idea was to add descriptions to summoner icons, so people actually know what they mean. Sometimes I see icons of other people or own icons and I don't know how they or I got them. It would be nice to have a description of sorts, see attached images.
While this feature might just look like a gimmick, I think it would add a nice level of transparency. It also makes icons more worthy to strive for as the option to see what it was rewarded for allows people to show off, as it adds extra value and weight to the individual icons.
The first two images are examples when choosing a summoner icon. The third one is an idea that when you are in the loading screen, you can hover over a players summoner icon to see what it was rewarded for.
EDIT: Also an important point is that icons have evolved to League of Legends own little achievement system to a certain degree. Thanks to kanacho for the comment.
EDIT2: CaptainMårvelous had the idea to add flavored text, this I added a 4th attachment SummonerIconIdea04.png as an example
