SOLUTION: Allow OKW to pick medics/repairing pioneers to be upgraded regardeless of the truck, so you can get medics if you go either Battlegruppe or Mechanised (but with Mechanised you will lose the luxury to have medics and ratreat point in one building in the lategame, because you will have to pick engineers in battlegruppe)
Another solution that occurred to to me during DBP's testing cycle is to change the order of upgrades on the trucks.
Currently you build the truck for its units then upgrade it for its utility ability. What if you did it the other way around?
Make the following changes to the Mechanized and Battlegroup HQs:
- Both trucks cost the price of the medic/repair upgrade to build (150 MP, 15 FU).
- Both trucks start with all their units locked.
- The medic/repair upgrade is replaced with an Activate HQ upgrade which unlocks their units and costs the original price of the truck (200/25 and 200/50 iirc).
- The Activate HQ upgrade is used in place of building the truck for the purpose of all prerequisites (build Schwerer Panzer Headquarters, call in King Tiger)
If you just want a Battlegroup HQ that can't build units it only costs 200/30 now (100/15 for the truck and 100/15 to build it). If you want to close the cap further you could move the entirety of the fuel cost to the Activate HQ upgrade, meaning you're only paying the 15 fuel for the SWS truck if you just want medics/repair pioneers.
