Nice idea
It doesnt have to be a 50 people server, 20-30 slots are more than enough, best servers on native are ZHG or Wolfpack servers with 30 slots.
So far people have to play siege servers to test their new equipment, which can turn out to be very costly. TDM servers dont have to bring money, it all about fun.
Are more servers good for a community? One server more or less won´t solve the general problem (not enough fresh blood in crpg)
