Disagree, how are you sure it'll give them that feeling? From what I see FGunz is the only good server, they can also see it as a "Oh SHIT I've been unbanned, let me play now, it's been a while", they can see it as a chance to go back playing.
And why do I defend that it'll benefit the server? Well, honestly, it's because we need to attract more PvP activity..
