or they could remove focus fire from mgs ?
Focus fire is set to false. This means it already tries to spread dmg when possible.
What i'm talking about is how suppression as a mechanic works. What we suppose to know about it doesn't hold true after making a simple mod and testing shit.
1- The more models you have in a SQUAD, the more suppression you will receive.
2- At even number of models been targeted, the lesser amount of squad you have the better. 6 squads of 1 model won't be suppressed as opposed to 1 squad of 6 models.
3- Accuracy, which should ONLY matter for suppressing other squads (blob), influence the amount of suppression applied to the individual squad targeted. This means that both, the size of the squad (RA) and the accuracy modifier on cover, helps against suppressing squads.
4- AoE suppression seems to be dependant on the amount of suppression been applied to the targeted squad. You can suppress squads behind cover by targeting squads around them outside of cover. In the opposite way you won't suppress a squad in the open if you target a harder to suppress squad (even when the bullets are going through their heads).
Note that this was all done with extreme cases of accuracy in mind (200% acc vs 1% acc) with 2 units with similar suppression values (MG42 was at 1% and MG34 at 200%).
