Hextech crafting should partially use IP
I personally believe that the Hextech crafting system should implement a small amount of use of IP. Maybe implement it with a purchase of key fragments for a smaller amount of IP. Also there could be a cap of two or three purchases of key fragments per month so Riot could still make some money but it would be "fairer" to be able to buy some pieces of a key, but maybe not an entire key, so you would still have to play to get keys.
