Just thought we can share with each other some tips here on what we've learned about mw3 gameplay, classes, maps whatever you think would help your fellow teammates.
One simple thing I've learned in this game which I think is really different from previous games is that a silenced weapon has no diminishing effect on damage in Core games so why not use it and add to your stealthyness. Since I've changed my classes my KD has gone up about 20 points in the pass 2 weeks.
Good luck and good playing. I look forward to reading your posts.
