I agree, Lowing the server capacity lowers the server rent fees.
However, I have heard of rumours that Server 5 is going to become a modded server, on an old Arma 2 map (forgotten name).
But again, I think lower the capacity so the people who do enjoy it in the community can still be satisfied, and maybe launch a server with modified addons to satisfy the other members of the community.
Make everyone happy is what I am trying to say!
