Things to do while not playing League

Sooo... I'm playing League for a whole while now (7 years to be exact) and I think, there are several things missing, that won't hurt either the Client, nor the playerbase or the game itself.

We all know, that its frustrating to get a Skinshard that is SUPER AWESOME but not fitting to what we play. For example: I got Reaper Soraka and a friend of mine had Lunar Wraith Sylas. We both love the other champions and would love to have the other skin. My Idea is to open a system, where we can just exchange Skinshards.

Also I still think, there should be more ways to get Essences. Both types. but thats another discussion.

Have a great day!
