Making the faction more symmetrical has brought balance to the game but I really did enjoy OKW in its early stage because of how fun it was to play, it was in no way competitive or fair for tournament play or anything but with friends I loved playing against them. UNpredictable. Having to deal with big pushes and the unstoppable KT while panicking frantically was an experience all right. Reminds me a lot of the Battle of the Bulge film (1965)
I mean, it's bullshit that they don't have to pay fuel for it like every other faction (or fuel for anything for that matter) but the grenade is pretty much fine as-is.
It still requires an HQ to be deployed on the field...
Brace should cost munitions. It doesn't have to be a lot of munitions, but at least a relatively small amount (such as 15 or 25 munitions). The mortar pit itself should have a reduced auto-attack range, but the barrage range should remain. I'd also recommend a pop cap increase for the mortar pit alongside a pop cap decrease for the 17 pounder.
I'd really love to see the flame hetzer get both a frontal armor buff and an increased damage vs buildings. This would give it a more defined role for urban combat. If these changes aren't added, I'd really like to see the CP go down from 8 to 6/5.
