You could say the same thing about high scores in retro arcade games...they started it

And honestly, I'm not sure when or why Disable XP was implemented; when I started playing PL back in Dec 2010, that option has always existed and to my knowledge, its been added in the past because some players wanted to keep their twinks at certain levels. We could just get rid of Disable XP altogether but that would probably piss a lot of people off, which is why I mentioned disabling kills as well. Had I been there when Disable XP was about to be implemented, I would've been against it, as that is the main reason why Leaderboards has been so skewed. Foresight is never 20/20.
