Skipping tech is the whole problem. It punishes the player who techs.
No one will disagree on that.
But i think the problem is less relevant for Wehrmacht because you only have access to Puma in 1 commander, you need tanks to survive while OKW players can get access to 3 strong units in Mechanized HQ. IMO its definitely a faction design problem.
I dont know if a OKW rework is possible but if so Battlegroup HQ needs to be more attractive and Mechanized less attractive. OKW rework should also include some changes to the commanders.
Commando Panther should be moved to a 2nd tier commander for example.
It was annoying as hell to see Mobile defense in every game last year but we see "Specops" in 7/10 high rank 1vs1 and that sucks hard too.
