New way to get blue essence?
What if, when we got mastery 5 with a champion, we started earning blue essence based on our performance in a game with that champion. For example: An S+ would give you 100 blue essence, while an D- would give you 5 blue essence. All numbers are experimental. This way, we don't have to gamble with chests for the essence, and instead, we can actually earn level 6 + 7 almost purely through skill. But that's just my thoughts on it.
