Meh. OKW's light vehicles and team weapons are underrated. The Rak is pretty bad at high level play but the MG34, Puma, and Flak HT are arguably top tier. On the other hand Sturms are garbage past 5 minutes, Volks don't scale, and Obers have low field presence. Really all OKW play seems to rely on waiting for the PIV J, the PIV J carries the faction when it arrives.
There is a major contradiction here. lv´s and support weapons are underrated but the p4 carriers the faction? so why not use the lv´s or support weapons? the okw LV´s do not fit. All allied faction have access to a light tank that can easily push the luchs/flak ht back with no impact and a lot of fuel wasted. if you go for a puma then you can beat the aec/stuart/t70 but then need to mothball it until the allied medium tanks arrive. all the while the allies gain infantry superiority because you have no obers.
As for the mg34. It works as a suppressor but not as a damage dealer or lv killer. the leigh is just worse than a regular mortar. and the tanks selection of the okw is just inferior compared to the ostheers.
