League Mastery Fallouts

Listen the mastery idea is cool right? You can play your favorite champ and get that nice flag and emote that say "I play this guy alot". But its missing its true purpose. It should show the people that play that champion well not just the ones who play them consistently. It would help players understand that they are making mistakes with that champion and not just "Oh here ya go even tho in your 500 games you lost to get this going 0/12 every game well make people think your good". Their should be ways to lose mastery points and rewards (borders that both teams can see) instead of a banner that say you play that person a lot. Chances are their are other posts like this and I apologize if its a repetition but I couldnt find one that actually said what needed said. So rito my old friend, instead of rewarding players for repetition dont you think you should reward them for improvement in ways that they can reflect on?
