What if weapon upgrades were changed so that focus fire = false like in case of a BAR? Wouldn't that help MGs so infantry squads don't insta-kill the gunner before getting suppressed? Instead they would be firing at all MG models and not just the closest one, or do I just not understand how the 'focus fire' mechanic works? Imho this would indirectly buff MG vs infantry and thus punish blobs more efficiently.
The focus fire = false scatter radius is quite small, I'm pretty sure it wouldn't make a difference against an HMG crew that's spaced out (like in a yellow crater or just in the open). Might occasionally make a difference against an HMG that's hugging cover, but only if the gunner gets targeted early on.
In infantry vs infantry fights, it would be a pretty substantial nerf to LMG squads. Focus fire = false is plain inferior compared to focus fire = true once healing stops being a big factor. Enemy models drop more faster, which means you do more reliable manpower damage and the DPS of your opponents squad drops off more quickly.
