Kind of disappointing level 6 and 7 mastery are based off points

Level 5 mastery doesn't mean you are good at the champion, and neither will level 7 when it comes out.

I was hoping to actually prove you are good: Level 6: Have a KDA of 2.0 or higher in ranked Level 7: Have above a 50% win rate in ranked

This means having this badge means you are actually good at the champion. With the current system eventually everyone will have LVL 7 mastery too so it will lose value as well. The only problem is people who don't play ranked. But how can you be a master of your champion when your not playing with people who are being serious.
