Before adding such improvements to OKW I would rather like to see the problematic (overperforming) OKW units and abilites being looked at first, mainly JP4, Stuka and Spec Ops recon flares.
If mines, FAUSTS and raketenwerfers arent enough options for you to hold off allied vehicles until JP4 or -depending on the map- panther is on the field, then you really just need to l2p
I had a good laugh this morning, please explain how the JP4 is anything but the worst TD in the game, I would rather have 2 Stugs, and SU85 or Jackson.
