This, there are just simply too many little things to argue over. Without official word from GMs on things it's pretty much anything goes =/
You just gotta adapt to all the cheap tactics and new exploits and find ways around them even if it includes another exploit lol
eg. A guild keeps running away with the gate rebuild I think it's fair to break it after warning
The only problem with that Bakken is that it escalates and escalates.
And just because you
think they ran away with the spawn point, doesn't mean beyond a shadow of a doubt that they did. Rogues are annoyingly able to sometimes evade the best efforts of people to watch the gate spawn. I know I've missed them at times.
And lets say, just once, you did miss a rogue, and then you killed their spawn point. Then they up the ante and kill your procs through the walls. And then you kill their throne through the wall. And then they jump over the wall. Etc, etc, etc.
Paying "hacks" back with hacks just leads to a bad place. That's my two cents, for the little it's worth. Retaliating just leads to dirty sieges and bad feeling on all sides. It's almost better to lose with honor than win with even fair foul play. Simply because it's a lot easier to call hacks than it is to prove hacks, to be completely sure.
