Well, I voted for the badges.... I know EXACTLY how hard it was for me to earn most of mine... And it's an easy way to get your x amount of kills with a kit, or knife, or pistol, or whatever.
That said... anyone who thinks that you get MORE points on K/P are NUTS.... Sure, you can get like what ? 2-300 points on a K/P server... But how long does a map last when noone dies ?!?!? Exactly.. so you end up scoring 2-300 points in an HOUR, meanwhile on the IO server next door. "Midas_ the_mighty_medic" (or whomever) just did 4 rounds of karkand/jalalabad/sharqi scoring 80-100 points in EACH round in the same amount of time.
Someone wrote that it's like watching the grass grow.. yeah.. it's fun for about 10 minutes, but 1-2 hours ?!?!? Shit.. no way. I've done it once, not doing it again. It's too boring, and for the big scores.... K/P isn't the way to go. In fact.. I think the IO mode has pretty much eliminated most of the K/P servers... There's like what ? 3-4 unranked ones left, and about the same ranked... Most of these are badly admined, so they're just CALLED K/P servers.... In fact, since IO, I can't think of a single badge or award that I wouldn't be able to get FASTER on regular servers with regular kits, than by using K/P... So Padding.... Nah...
