Ability to purchase more space for friends

(this is a repost since the previous name was misleading)

So, this is about people that eventually hit the 400 limit on friends. Im still not exactly sure why League made a cap on friends in the first place, but for streamers and friendly people its comes up as a problem down the road. the easy temporary solution would just be increasing these limits but they would just fill up again. I suggest that Riot try selling expansion to friends and maybe chats for rp. Would be awesome and so helpful. thanks for taking the time to read this.
