There are way too many bugs still in this game that are incredibly easy to exploit. Stat padding doesn't seem like that big of a deal compared to many of them. Most of them have to do with rendering, or the lack of. Shooting through AMP station shield takes almost no setup. There are also HP bugs that grant specific players massive amounts of hit points. I'd rather them deal with those than some number on a leaderboard that doesn't affect anyone. Plus if they're going to run the leaderboard correctly they'll archive and reset it every 6 months or so.
