Not really.
Yes, you may have an advantage when it comes to reflexes and actually being able to aim, yes you may have an advantage in quick battle situations but that's a small part of this game and that does not qualify as being good. I'd call myself a decent FPS player and I do have the upper hand in lots of battle situations but I wasn't helping my team, I wasn't winning us the game, I wasn't getting any points -- I was basically just getting kills for my own satisfaction 95% of the time and then being 'good' means fuck all.
This is one of those games where they actually promote everything else. Plus, some "good" players are good with all the recoiless laser rifles and when you can bunny-jump-super-sprint all over the price, both of which isn't really the part of the feature set in this game.
So camping somewhere getting 1 point kills does not mean you're good.
