People who actually takes their RP seriously and out effort into it, to answer your question.
I'm not one of them, I do however respect certain factions enough to out effort into RP before PvP. The exceptions are extremely limited and I'd like to keep it that way for my fun's sake. Even as an indie, I would still try at least.
But the point is, uncontrollable indies are cancerous and no one seems to be able to do anything about it. Which is what makes them cancerous. I was "hunted" by these said indies before for oorp reasons, I don't see why would they stop now either. This has been going on for nearly a decade now. The change to official Zoner factions only is harsh, but good. It will teach the 13yr old Nephilim captains to know their places.
