Well I totally disagree with the above feelings..
1) cant ban people for doing tehse things and thats not a fix.
2)You cant stop reds from killing thats what reds do.
3) You cant stop blues from using safe zones thats what alot of blues do...

Here is a somewhat of a fix that may help..

Why not just make the gates larger..like 2 of them..that way there wont be enough players to be able to block it .. And add a another gate at the newbie dungeon so people can go out up there and avoid the bottom gate and the cemetary..

As far as reds go , you cant limit where and who they murder since thats the choice they made and how they play..
And you cant stop blues from running into town and performing gorilla warfare...That would stop if the reds didnt hang out in gate zones.. The truth be told people hang out there because there is a ton of action there and its fun!!
