You're supposed to be rewarded for playing well, yet Riot always take the wrong initiative in their ideas as they want to make the most money and also cause dis convenience.
I currently have 3 Champions ready to move to their next levels and i cant because:
I don't have the IP for champion shards
I don't have the Essence to upgrade
I'm not going to spend RP on chests
Champion shards are a gamble and the essence gain following it varies
Why not just give people "X Amount" of Essence per win? (Lets say 50) Since Riot like the idea of people playing together so much, why not give them bonus Essence for partying together? Each player will ad the bonus up to a max of 30% = 65 Essence per win
