In an event must have rules, and PK in a constest where is suppose to kill ONLY mobs, not players, pk is out of question about this particulary event! Because is about teams for mobs not teams for players, if so many ppl don't feel good about it, do not participate then.
If PK is such a problem on making the game more funny by creating an event then GM's or someone else MUST create an event for Pk players such as team pk events..! Like in 200x server there are some events maded by GM's and is not allowed pk as well. People in 1000x server have like Arena if they want so much to kill each other, but I see that the problem is by killing other players there is no reward.
If thats a problem should have a PK rank such as Reputation, like constant buff from the top players.. (unique buffs) or something like that. This is an idea that Gm's should listen.
About the contact, if you don't see me online send me a mail that we will meet in a certain hour
I suppose this should be created even in 1000x server because it breaks the routine, and the cooperation must be by ALL players.
