All other factions need to pay something in addition to tech to get healing, no freebies, OKW is not nor should be excluded in any way.
That is the whole point of having them as an upgrade.
And why the tech itself should be cheaper with a unit locked additionally?
There is no reason for that.
Every faction has to pay for their healing.
Sov has to pay 250MP
Ost has to pay 150MP + 60MU
USF has to pay 237MP + 7FU
UKF has to pay 60MU
OKW has to pay (100MP + 15FU) + (200MP + 25FU) + (100MP + 15FU)
The total is 400MP + 50FU. As expensive as that sounds, it's a tech building you can shove somewhere on the map that comes with medics. Add 300MP in, and you can cut the time needed for your troops to return to the frontline unless you park it inside your base- In which case, you won't need to pay 300MP.
Or, if it's too rich for your blood, you could just spend munis to heal 3 squads on the go.
firstly, there's a
big difference in only having 1 medic compared to 3 medic. It's not like the AOE heal for the USF and UKF where the number of entites do not matter.
medic heals like the okw, wehr, and sov require the medic entities to heal wound soldier one by one.
Anyone who ever have to share healing with a team mate will note that You can easily overwhelm the three medics with wounded.
and it's not really "free" it's still packaged into the cost of the medical truck + the unpacked truck.
If the flak ht get locked behind the theoretical improved healing upgrade, the okw will just be getting the mg + leig + 1 medic with the base medical truck.
This would make medical truck + light vehicle support more attractive as an option. If you just go pure medical truck nothing would really change.
