Great $$ Idea for Riot
So, over the past couple of seasons a lot of the changes have led me to believe that Riot has been pretty intentionally and pretty significantly catering changes towards the casual player base.
So here is my idea for them to make money so that they don't have to worry so much about losing some players.
Exclusive cosmetics available only to Plat and higher players that still cost RP.
Boom, problem solved.
Edit: I'm not saying we should remove purchasable cosmetics for casuals. I'm saying in addition to their regularly scheduled skins and their annual victorious and worlds team skins, Riot should also release a couple purchasable skins, ward skins, and emotes that are purchasable with RP and unlocked with rank. No removal of content or buying power for casuals, just a little added buyable content for the higher echelon.
