spies are plenty strong with ff off. Its easy to get kills with them if you know how to play them right. I would say its possible that they would be too strong if ff was on. Its so easy to backstab half the opposing team before they realize you are there, especially in servers with max populations of 11 or 16 or so.
In other news, when is the server going to be operational? I tried to join a couple days ago and it said i couldn’t because of different versions or something. I never see anyone in it.
