Not sure what your trying to say, but here's what I got the gist of.
Hey, there should be more free summoner icons. Even though I have to spend real money for the ones that are in the shop that have a semi-variety of icons.
[ there is a penta-kill icon you can buy ] But giving an icon for 4-5 straight kills, isn't that rewarding. Maybe if you got it 10 times in different games, or 3 times in one, eh.
For you, so this is about you "me me me I want"
That Idea has flaws.
1.) If they were to let you use icons for ranked groups, it would be from the ones you have.
2.) I have plenty of free icons over the years.
3.) Riot doesn't even have customization for banners, so I doubt they will implement ranked icons selections, besides maybe the league your in.
4.) Riot doesn't enter too much personal customization, so you being able to "create" your own icon, may cause problems with trolls doing troll things, and probably need a giant data base to allow them to keep the custom icon and let it be seen by others.
"So I should have an icon for that" Wut. You saying you deserve an icon for being in a ranked group. No, you get the icon and banner at the end of the season you are in. That should be enough.
