Rekketen question I think its ROF is clearly an issue as well as its detection range. I think if we increase its detect-ability as well as maybe its ROF (either of but not both) would help deter armor but also not over punish b/c light vehicles cant back out quick enough before the second shot fires.
Its ROF is already the worst of all ATG along with the ZiS-3.
I would much rather have normal 60 range, slightly better aim time and decent crew protection. Then the stealth can be stationary only.
Sturmpios I believe the unit is fine outside of their early ability to grab a building and ez pz lock it down. maybe a 20-40 muni STG upgrade would work to help scaling.
Early aggression is also the only merit of Sturmpioneers, as they get outscaled very quickly by vetted/upgraded/concentrated infantry and after that point they become just really expensive engineers.
Counter-less recon is defo a problem and I would like some sort of way to counter.
Allied flares have the same problem. Recon flares should be reworked to just be a visual clue with the actual ability being increased sight range for units in the targeted area.
Obers I believe are fine.
Obers are not really fine, they come out too late and have a lot of trouble going up against vet2-3 enemy infantry. OKW T4 should be split up so Obers can be deployed much earlier from a 150MP/50FU setup with the AA gun upgrade, Ober LMG upgrade and armor being behind a 50MP/70FU upgrade. Moving Obers down to the early mid game would probably also allow for Volks opening to be nerfed a bit.
I believe some form of these changes / edits would help even it out but ofc not all of this has to come forward and OFC stuff is always up in the air but I agree OKW is rather easy to play compared to OST and allies. Thats not to say in 1v1 they aren't hard but 2v2+ they surely aren't as punishing as other factions.
OKW has plenty of gaps in their lineup that makes them arguably harder to play mid/late game than the much more rounded Ostheer, such as lacking a good AI vehicle or proper handheld AT infantry. It doesn't help that their HMG and ATG are basically trash (with camo cheese being the only thing that makes the ATG somewhat usable).
