Am I missing something or is there no really good reason to prestige past level 9?
As far as I can tell you get nothing for Prestige 10... except for some lame emblems I will never use, and beyond that it's just other useless crap such as facepaints, colored clan tags, and gold guns. I mean, really, gold guns? You go through all that and all you get is useless gold gun camoflage? And just where the hell are you fighting a war where gold is "camoflage"? El Dorado?
Seriously, is there any material reason to prestige any further once you have all your custom classes?
