I've played this game for about 5 years now. At this point in time a I have all champs unlocked and have no more use for my IP. I can do an other namechange, but that's not what I want.
Maybe riot should implement something into Hextec crafting where its possible to buy an IP to RP chest. This chest can contain a champ shard (65% drop rate). A gemstone (5% drop rate) And 500 RP (30% drop rate). This for the price of 4000 IP or something similar would be a good implementation into the game.
I feel like lot of others will have the same problem with their IP. Post your idea's aswell!
