Quote ECR regenerates at a rate of 25% every 24 hours, or 1.04% per hour.
So the optimal would be to have a bot that plays roughly 1 or 2 battles a hour per accound. This is what multiple bot accounds easy could achieve but is a chore for a human.

I do not know how exactly how the ERC drops per battle but i have the feeling it is ~1% relative to the ERC available.
So play 10 battles rougly 9.95% ERC decrease.
After 100 battles "only" a 74.4% decrease.
This mightbe the reason i see bot accounds have low DEC rewards, but never really 0.

why give new/low league players more potions?! New players need some progression to stay. If you want to give less rewards to bots, do so. But this is hurting new players more than bots, from my point of view.

Can we finally get the statistics on the bots?
