Abysmally low amount of BE per game...
Just want to bring this to attention: let's think about the fact that if you're 15 BE short of a champion in the store, you'd have to play 10-15 games to buy them - the only source for BE being leveling up is unbelievably stupid, and it is a de-motivator for new players and even somewhat experienced players like myself.
