For some reason it feels like my lv10 companions of lower rarity consistently give me less pebbles than when they were lv1 or even companions of the same rarity tier that are lv1. I just played with my lv10 kapura and it gave me a whopping 27 pebbles. Lv 10! I am already quite iffy about the fact that the KS exclusive companions give so much more than those that can be obtained through gameplay, and that even the moonstone exclusive ones give a lot more than the pebble-bought ones. But while their payout does seem to increase as they level up (although I still get a low roll from time to time that ends up being lower than when they were lv1), it just feels plain unfair that the more common, readily available companions, when levelled to the current available maximum level, give 27 pebbles.
To start mending this huge disparity I feel like with levelling up, the lower limit of possible pebbles you can get should go up.
Say a lv1 kapura can give you beteen 50 and 150 pebbles, with the lower values having a higher chance. A lv2 kapura should have 60 - 160 as the lower and higher limit, lv 3 70 - 170, lv4 80 - 180 etc. etc. I'm just plucking random numbers out of thin air right now, purely to demonstrate what I mean. But I feel it is ridiculous that my lv10 kapura is giving me less pebbles than it did when it was lv1. It makes it punishing to actually level up (when levelling up is such a necessary thing for other parts of the game, like hunting, the campaign and the guantlet!).
I personally also think that the difference in payout between expensive companions, like the KS-exclusives and moonstone-only companions, and the cheaper more common companions should be lessened. It's too pay to win and rich get richer while the poor get poorer. If there must be a difference in payout, I think those companions should at least be more difficult to level up (more xp required per level)
