Treyarch has a history of making good LMG's and even adding guns to classes they don't belong in to make the class better
On Black Ops we had the beastly M60, the Stoner, and even the RPK was good --- This Sig is the property of this distinguished gentleman: http://i.picasion.com/pic51/86515ed5bbd652ac424eeea2d33c8939.gif
I loved all the LMGs in Black Ops except the RPK. It's just barely above the UZI in terms of usability. --- Kept you waiting, huh? Currently playing: Half-Life 2, Vampire: The Masquerade Bloodlines, Persona 3 Portable, Legend of Dragoon, Alice: The Madness Returns
W@W had a wonderful selection of unique LMGs that were mostly pointless in light of the SMGs. BO had a pretty sorry lineup of LMGs that were mostly pointless in light of the ARs.
Hopefully Treyarch has caught on. Simply kicking their habit of giving LMGs <50-round mags would help the weapon class SO much. The Stoner and HK with 80- or 100-round drums/belts would actually have a point, for example. --- Oh the movie never ends... GT: IHOP 13
