Fucking Operation Metro is the worst thing ever. I actually like Operation Locker, but I couldn't even get 10 kills or a shotgun ribbon on Metro 2014. God damn it why did they include that snooze fest.
I've actually noticed that I suck at all of the Second Assault maps. Caspian Border is alright but I get terrible k/d on Oman and Metro (haven't put much time into Operation Firestorm yet). Might have to go play some vanillia/China Rising maps for a while; try to get my k/d back up a few points. I really shouldn't care about my k/d, but I really do.
