Post - Mastery 7 Ideas?

So, I main support and it's super easy to get S's. I was thinking of certain "Challenges" that riot could make per champion. For example:-

Thresh

Land 100 hooks Flay 200 enemies Save 200 allies with Lantern

Bard

Stun 100 enemies Ult an allied structure near death, then keep it alive for 10 seconds Heal 1000 allies

Just a thought, obviously numbers need work but you get the idea.

Peace.
