Well, at the same time, griefing is much more prevalent, which is what I used to experience way back when. Get in an equal fight with the guy, kill him, do it again, kill him, so then he gets pissed and follows you everywhere, vulches you on landing, rocket-kills you when you try to take off, and generally messes with you until you just wanna go back to hoarding.
It's much easier to single someone out in an arena of 15 players than 200 or 400.
