lol sometimes tbh. Not sure if you're trying to convert any of us though.
On Hijacked when I used the QBB LSW I put rapid fire on it just to make sure people will drop when they should but I don't really like enjoy using an LMG in 'modified' roles. It just doesn't feel 'right'. When I used Quickdraw on the MSR in MW3 I felt the same. :/
As a die-hard LMG user I honestly say they do not need any buff (although any would be welcome but that would push them towards OP) they already have many good points(damage, range, wall penetration, recoil, Mag size), the only bad ones are the mobility and handeling, if used correctly all LMGs are deverstateing.
