I'm not near my xbox right now, but my suggestion for getting to higher rounds is to play solo and train in the Buddha upside down room. below the AN-94. Grab galvaknuckles early if you can so that you can get 6 perks with the perk bottle during hell-crawler rounds. Get a PaP'd AN94, sliquifier, and a third PaP'd weapon of your choice. Just train for days in that bottom Buddha room and you'll be good.
Addressing your topic more directly. I'm actually interested in playing, probably some time tomorrow if possible.
