I am not sure if it's suggested before but having the option to schedule the bot to swap region would be nice. Card collections aren't saved over multiple regions so you have to farm each region separately. I think it would be a nice incentive for users to purchase the bot since the trial time would not suffice to farm 30 wins on every region.

I am not a coder but it doesn't seem to be difficult thing to just have it swap regions since it's directly on your Hearhtstone window.
