These wars you guys speaking about, how can they be started over and over again? Basically if you died during the first war can't you enter the second once as that's qualified as revengekilling if you don't have a different reason then last time.
To be honest, I'm tired on these "wars" between groups. In my view is it players who are happy triggers and these situations does so Argonath continue its travel towards a new Paruni version. I've noticed it more and more, so have others. I get lots of complaints about larger groups daily that is deathmatching, revengekilling, cophunting and so on. What is your goal with this? The only thing you do is to drag down Argonath in the dirt, nothing else. Do a gangwar, sure, but if you don't have any roleplay reason more then "We are in a war" will I let my punishment-hammer slam in your head.
