this sounds like a bad joke.. as if instant surpression MGs and aimbot mortars still need any kind of buff..
I think you are not up to date, cause aimbot mortars are no longer a thing and if you are not using barrage constantly they perform piss poorly.
Which is why i don't suggest buffs which improve their dmg output at all.
In the same vein, MGs performance early game is fine, but once you start to use artillery or the game drags on for a long time, light cover just makes pushing MGs frontally too easy.
The maxim is the most affected by these, because it has the worst time to suppress of them all and light cover just duplicates that time.
I don't know how many times it has to be said: MGs teleporting on death is by design. We can't change behaviour of the maxim on retreat, so it doesn't matter how many times people complain, buffs to maxim have to come from a different approach.
