There is no faction on this server with that edge that I know of, since XP merged into artifex. You complain about no PK and that there is nobody to "challenge you", like you're some sort of unbeatable team, then why did you merge your only real challenge into yourselves? The logic is flawed.
because XP was hibernating, wasn't going to PK anymore with Insanity and Silence as the lead
XP didn't disband to join arti, most went to OC actually
but while that all happened some became friends with pedro and few others in arti (since they recognize after all that this is just a game and they don't have to hate a person so much because of the guild name above their head (
most of the time anyway)), and since they were bored decided to join arti
and since those few friends joined arti, a few other core friends decided to join with them
and then there we have it was a happy ending
so no, even if artifex hadn't "merged their only challenge" themselves, the same xp wouldn't have given them pk
