A new idea for champion Mastery

Mastery is one of my favorite things to get on league, I love to be able to shine it and show my experience on a champ. I had a neat idea about maybe combining champ mastery with the end of season rewards. Basically, say you received mastery 5-7 on and say ends up receiving a victorious skin like Sivir, at the end of the season. What if you earn a special mastery emote that shows you were skilled with this champion from before the skin was released. Another thing I thought of was, maybe just add different mastery crests for each rank you got from last season. Flash that bronze pride if you end up getting gold next season!! I would love to see these implemented because I love how mastery works and I'd love to hear what everyone thinks. -DeathlyMonkey
