(adsbygoogle = window.adsbygoogle || []).push({}); They need to be able to level up by playing zombies. In WAW i found it kinda stupid that you dont gain ANYTHING from playing zombies online. They need to add like get experience from the game so we can level up. In waw im like leve 12 if they would've added xp to the game i would be like 7th prestige or something.

that would be good

Seperate ranks would be pretty good, but I don't see the point in having a rank at all? Unless you could unlock certain 'abilities'? Like carry more magazines, or run longer/faster... More health?

nahh, you deserve points for killing humans, not the computer ai. That's kinda dumb lol.
