Ok... I'm not satisfied with how we currently can grind BE.
First Win of the Day only gives you 50 BE... **50** !
I'd like to earn BE whenever a match ends (either Victory or Defeat; either SR, TT, HA, Ranked or RGM) or through Hextech Chests (either raw BE or a guaranteed champion shard).
You can remove the 50 BE on FWotD if that would be "too much".
There are a lot of players like me (most of them new) who still don't have all the champions and disenchanting champion shards that you barely get won't help you with that.
Tell me what you think of my suggestion and how else Riot could improve the BE system.
