Thanks for your suggestion! We had normal community servers before, where users could play and earn points at the same time. But we removed them because they were barely used and it was too much work to maintain them. So we are not planning to bring them back, sorry.

There should be actual play/community servers aswell, so you could play tf2 while earning coins. And if u went idle in one of these servers you would be sent to the idle servers.
