Champion Mastery Icons

I don't know if this is an good idea or not, but i just though of Champion Mastery icons: icons you can purchase for IP in the shop for every champ you've unlocked an Mastery Tier with. Im thinking like this (i don't know about the prices, if anybody have better and better idea how much they should cost, tell me): Mastery lvl 5: 3050 IP Mastery lvl 6: 6100 IP Mastery lvl 7: 12200 IP

Like i said, i don't know if this is and good idea, let me know what you think Thats all for me, hope some nice people from the community read this :)
