I spend most of my time battling bosses on PRO therefore due to the update I will now be spending lesser time on PRO. I am thankful for the update on having 10 per week limits on battling bosses, it allows me to spend most of my time on more important things like being with friends IRL and doing some other stuffs I like aside from PRO. I also suggest since you guys don't want players to spend most time on battling bosses and you're afraid of them getting rich IG why not just remove other bosses and leave only few, some bosses are of insignificance anyway, pumpkin king for example. "Keep in mind that Pokemon consists of four basic elements: Hunting, Training, Trading, and Battling. The boss battles were created to provide additional, renewable content for players who have already completed their story. They were not created as a means to provide easy, consistent shortcuts to avoid the four basic elements of the game. The cooldown is to ensure that some things don't enter the game quickly, namely some of the more valuable rewards."
PS: I would also suggest to keep track on number of players playing after this huge changes and compare it to the number of players playing before the changes. Whatever the result maybe, the decision whether to withdraw the changes or not is yours.
