Imo they should do following:
-every 400k xp you acquire, you gain 1 point in EACH constellation, reducing the overall grind by 3 times
-so instead 3600 points we would need xp for only 1200. Which is also preety big number, but much more tolerable esspecially because of the Diminishing rates when spending Champ Points
So the number is still preety big, but you will feel more proggress with each point
