M3 or M20 hardcounters it quite well. I have to admit that the small arms penetration is very RNG dependant, sometimes a con volley brings it down to 3/4 health, sometimes it doesn't. You also have to remember that there is one less infantry squad on the OKW side early on, so you should be able to win those engagements.
I like the Kubel's new role and I think it's fine.
So for example if your order a squad to capture a decrewed weapon like an AT gun and shift click retreat, so that they retreat as soon as they capture the AT gun. If they get supressed while doing so they immediately retreat. This causes a little bit of frustration because they still might have gotten it.
The fact that you automatically have to download all the faceplates and decals of your opponent is very annoying, my inventory is full of anime faceplates.
1/4 of these guys are roughly playing the gamemode you are playing right now, something around 1700 players. Most of them are playing with random teammates, but let's say it's 50%. So good luck with matchmaking with only 850 players searching.
Blalord is right, the playerbase is simply too small and too divided by diffrent gamemodes. It would work if all of the players played a single mode. Note that probably a good bunch of people are playing the AI/Campaign aswell and that some gamemodes like 4v4 have a higher percentage of players compared to the rest, so there are most likely even less people in the queue.
