I don't play as OKW but here are my thoughts after playing every single game against them.
(Currently in 2vs2 you only see double OKW teams)
Kubel could probably use a bit more love with a slight health increase and better performance on the move to help deal with Soviet sniper teams
Kubel needs a improved pathing. It's a good unit, but all its good things got eclipsed when it starts to do retarded moves.
I honestly think the infantry gun needs a slight tone down, This gun is simply an MVP every game. It has great vet scaling and can direct fire against light vehicles. Its simply fantastic and probably a little over preforming its cost
I think infantry gun is fine. It doesn't need a nerf.
Inferred sights on the Obers is way too much. You will loose a squad in a blink of an eye with their ignoring cover bullets. The cost should come down significantly and so should the effectiveness
Obers are fine, but ignoring cover is a stupid mechanic that should be removed.
Lets face it, the OKW puma is way over preforming. I think the Osheer one always has as well, but this one is better for whatever reason like the panther. well microed it can beat most heavy armor.
Agree, it overperforms. I suggest less penetration and smoke moved to vet 1.
panzer Fussiliers
I don't have any problem dealing with them as soviet.
Can we please reduce the damage the stuka fuss does?
The unit overperforms if compared with other mobile artillery. Instead of nerfing Stuka, I'll buff katyusha and pzwerfer. Maybe less cooldown between barrages for both.
reketenwerfer
Raketen is fine. Maybe it'd need to shoot a little faster.
Infiltration grenades
Yes, they need an ammo increased price.
Pak 43 for both Ostheer and OKW needs a significant range increase to make it useful.
I don't know. I don't see many of them in my games.
OKW flak halftrack needs a little looking into. It for some reason has huge issues actually hitting anything other than debris or the ground, a problem that many tanks share but it is by far the worst on this unit. It also needs to have its set up time to match the M15. Its basically unusable at this point because its set up and tear down is so long
It needs a shorter set up and maybe an armor increase. It dies too fast.
And I'll add that Jadgtiger should be revised. The unit would be fine if OKW infantry wasn't so powerful, but Jadgtiger negates any allied tank play and then Obers and elite infantry just rape all remaining forces. Jadtiger forces soviet to choose an ISU doctrine, which is another tank that should be nerfed.
Try to see how many T34/76s you need to destroy a slightly supported Jadgtiger, even with Mark Vehicle and good flanking.
Such monster units are the reason you only see call-in tanks when playing against allies.
