If suppression works the way it did in DoW2, it increases the cooldown on the unit by like 20x.
Maxim has the highest ROF and probably lowest cooldown or whatever so isn't hurt by this as much.
It's dumb because Maxim vs MG42 or vickers maxim always wins hard.
Yeah, I think it's because Maxim suppresses a single target it fires a full burst at pretty consistently so the suppression penalties are irrelevant to that (X4 cooldown, reload and X0.25 accuracy). And with the heightened reload times from suppression, reloading HMGs will give even pinned Maxims time to recover and shoot again so the Maxim will proceed to win the silly HMG duel with their superior single-target suppression. Once the other HMG is pinned, the fight's probably over because of said single-target suppression.
