[2022] Even at 400k mastery points and with the champion mastery token, I risk having to wait months upon months to get blue essence to advance

I have 58 blue essence, I didn't get any OR a champ in my 2 last chests and I have, with 6 games today and 9 yesterday, gotten no chests nor keys. I could start spending cash on chests but even then, you risk having to by dozens of chests.

This doesn't feel like being rewarded for playing well at one champ at all.
