Getting BE Only From Levels Doesn't Feel Good

So okay I want I usually set goals for what to get in games and I like when you can have meaningful progression towards those, but to get Camille, depending on the RNG, I could get her in one level via a shard or 2 levels if I get lucky with the shard rng or in 3 levels with basic rng.

It just doesn't feel very motivating to see the level bar go up little by little, it feels like an eternity. Even getting like 5 BE for a loss and 10 BE for a win would make the grind more meaningful and rewarding, and gathering that passively while playing champs you like is a good feeling.

I just really don't like how the progression is tied so hard to lootboxes and rng that it doesn't feel like consistent progress. Thoughts?
