Fonza, the issue with making it the faction leader's responsibility is that some faction leaders, themselves, basecamp. I hate to say it, but we can't expect those people to enforce a rule that they won't implement because they want to keep doing it.
New people come in, get base camped, and get told it is allowed. Those new people leave and don't come back, and I can't blame them. If I joined the server as a fresh 11B and was told that base camping was ok, I would of left and I wouldn't of looked back. The only reason I stayed was because I didn't experience it until I was already in GB. Eventually, new people won't hop on, and the server will die slowly. Staff need to step in and resolve this, or this community will die out. Don't put it on faction leaders to put a rule for their factions, when it should be the staff enforcing it as a server rule.
To the people saying "Just use the other exit and flank that way". It doesn't help when they set up a second basecamper at the other exit, it's almost like they coordinate it.
I have to disagree with Towelie's statement "As long as snipers exist, base camping will exist.", as some of these snipers deliberately are moving TO US base, when they really should be at the OBJ or off center of OBJ.
I have already made a forum post about this, and it was technically accepted because of the spawn protection they added in, which really does fuck all when you take two steps out of the base.
Staff, if you want new players to stay, fix this. Don't rely on faction leaders to do it for you.
