No doubt the smart people running the bots will adapt to this new reward system, however I believe they would have to stop grinding as it becomes uneconomical once your ECR drops below 50-60%. I have lost to bots who have 1% ECR that get no DEC and no RP. Also the RP scales up quite a bit once you pass the 15 chest mark, so if you are not winning in a higher league compared to your previous league, it basically a waste of electricity.

That being said, I think this change to the reward system has been fairly well implemented. But definitely need to wait a few seasons before coming back to look at it again.
