If you can't give more bling instead of random cosmetics, then why not only remove the random cosmetics all-together and relocate the bling back to PL? As of now there is no real incentive on playing the game after the 8 wins for Starr drops. Even if most casual players don't play power league, giving away half of its rewards for (almost) free would only be eye candy if anything, because everyone is essentially getting the same rewards, not any actual advantage, and sacrificing so much time and effort for a slight advantage on bling is just not worthy.
The randomness is the actual “fun” part of the rewards - I understand it might be subjective, but we believe the casual player do like this feeling of not knowing what they will get from a massive pool of items. And if we are wrong, we’ll adjust the system so it does feel exciting
There is an actual buff to the rewards also, it’s not only transferring from one system to another, but if before you were struggling to play PL just for the Bling, then the problem is not on the reward side, but because it seems you consider playing PL a struggle
If you keep the same playing time as before, you should be getting more overall, but it’s true that if you were really active and engaged, the buff is not that much more, but we want to see how it goes now and we are open to tweak rewards around if they show they are harming the game more than making it more fun
