Classic servers are actually doing pretty great, even when removing the bots! We are also at the end of the actual update so of course many players won't be back before 2.0.
Regarding DPS Meter, I can understand why some people don't like it. It is sad that it can be used to refuse people but it is also a useful tool that can allow someone to see what needs to be changed in order to perform more. That second part is the main reason we tolerate those.
DPS meter is good to improve ur self but ofc it should be used as ur own gain not by harrasment other players! That should be equal to an ban its still a 3rd party tool program..
