Back to the gun talk, specifically LMG's.
Maybe it suits my playstyle, but I seem to destroy when using the LSAT. I didn't add any attachments until FMJ. I was able to get 2x triple kills in the same game probably..... 4 times in a row last night? Beyond that, I noticed a significant improvement in K/D. I am level 32, still consider myself a HUGE noob to this title, but damn that gun is great.
Play Ground War and Hardpoint almost exclusively. The LSAT has given me a renewed faith in MP
