the ISG and Packhowizter are getting overbuffed.
Pack howitzer doesn't need the suppression. The USF already have the .50cal and the m15 AAHT for suppression. They don't need the pack howitzer to suppress as well.
The problem with the ISG is its range. Its long range make it easy for multiple isg to establish overlapping field of fire.
Pak and ISG need the suppression to counter blob. Otherwise pack and ISG are useless because you can run on and the unit has no way to escape. Or you give them a retreat button.
People are focusing on the suppression when the suppression isn't the problem, the problem is the killing, sniping from far away.
The pak is in the good spot because of it is high cost high value unit requiring some micro and it has a reduced cone of fire. It also doesn't have a shield protection and can be easily depop.
The ISG has a huge range, combined with the different OKW truck make it unattainable before your T3-T4 which is completely silly. It also doesn't have any cone of fire, it simply fire a 360 degrees and have a good shield protection.
Now its price for a faction floating in MP combined with the above make people spaming it because it simply wort it.
Increasing their scatter will simply make them useless, you have to consider them as MGs, they shoot, they suppress but they shouldn't kill so fast. Since they don't have a retreat button, they need some distance but far less than 100.
ISG: add a cone of fire, reduce the far distance to 60-70, reduce the damage per shot, remove the pin
Pak: reduce the damage per shot, remove the pin
So having one will still be useful for two factions lacking of blob control but you'll need more micro to use them, actually a lot more to use the ISG which is today one of the reason it is spamable => no need to micro it.
