Riot knows Blue Essence has lost meaning for LoL veterans and is working on changes

Riot Games is aware the Blue Essence players earn simply by playing League of Legends loses its value for those with older accounts and has declared it’s working on a way to make it more meaningful in the long run.

Blue Essence is one of two currencies in League, and it’s one of the easiest to earn. In the beginning, Blue Essence is a crucial currency because it’s a great way to unlock champions and expand your champion pool. However, as your account grows, along with your collection of champions, the value of Blue Essence quickly begins to diminish.
