ikr, i think they should have a sytem similar to BFBC2 where you earn points towards a class of guns, assault rifles, smgs, snipers etc. and when you reach enough, you unlock an attachment for every weapon in the class...

I like the list...a little long, but some good additions. Mp7, glock, ak74.
However, I would like to see IW take out a lot of the old "fan favorites" and start fresh with some guns people haven't used in a contemporary game. I miss the feeling of getting online for the first time in cod and not knowing which gun suits my style. Unlocking the next gun and having to immediately try it out because it could be better than the last. This has been lost with me over the last few games. An mp5 is an mp5 and an ak is an ak in the last three games, I know how they look, I know how they feel, and other than a few minor adjustmens to the sound and recoil, there's no excitement in unlocking them anymore for me. Don't get rid of all of em, but I would like to see a majority of the guns in the next game be completely new.
