First, to address Ganging, not for nothing, but this is a PK mud. You're character is going to get killed. It's going to happen.
Second 2v1 is not a gang in my opinion. Yes, I've been tripped to death by two people. Yes it pissed me off, but you know what it pissed me off because I could have prevented it, and easily. There are skills in this game which at time will seem OP until you play them. Assassinate comes to mind. So stop complaining about that guy who just gets you "every time" with that assassinate, until you play an assassin and actually see how tough it is to land them.
Third, I don't care which cabal your in, you come to the general vicinity of another cabal and pick a fight with one of it's members while they are defending or retrieving, do not expect it to be a 1v1 fight. ain't gonna happen, not in the village, not in the fort, not in the spire. You pick the fight there, be ready for that cabal to jump on your shiz until you give up and go way, kill them, or die yourself.
You want fair, go play another mud, stop whiniing about fort gangs. Cause next month it will be Empire Gangs, the month after that it will be Nexus Gangs.... Figure out how to survive in those situations, learn to play better.
