Why not just put the Mastery Keystone icon on the champion's portrait itself?
This is an example from the LCK matches, where a champion's portrait would have both his Ult & Mastery Keystone beside it. I just love to see this, as it should settle the trouble of what champions has what keystones. But for some reason, LPL & LCS does not have the same function.
Could you imply this change to the current games please? I'm tired of having to memorize which champions have which keystone masteries by reading from that 10 second appearance.
