Its basic balancing/design knowledge that LMG's are not about mobility. They are about firepower/extended engagements. Holy crap, how do you know that 0.75 ADS + HA shield activated(while ADS) unbalances the ability? You went full stupid, never go full stupid. Your actually correct on that. On Pistols & SMG's its fine. Even some carbines(or AR's) 0.75x ADS is alright on. But It shouldn't be on LMG's, Shotguns(since its mostly hipfiring or when using slugs you are not ADSing around fast) including the Jackhammer(which is a heavy weapon), Scout rifles(Vandel) & the Archer(which is hilarious seeing this big *** rifle strafe around).
