Because that is how the faction is designed from the get go.
Deal with it or play faction with easier access to healing, but no free AA/area denial/durable FRP.
OKW have plenty of other things going in their favor, which other factions do not have as stock options.
8 min stuka? Rushed katy is what? 14 min? Want to discuss the costs of getting pwerfer?
Factions are getting different stuff at different times and at different costs.
Either backtech for med HQ, like everyone always did, because this is how you play OKW, or spam med crates with all the ammo you'll have saved on shrecks.
Wow you really don't get this do you? It is becoming futile to debate with you, but I will try one more time.
As the faction was originally designed you got trucks dispatched for free. FREE. Then in the big redesign they added a cost for dispatch. So when you say the current cost for back tech is how faction was designed, you just aren't talking straight. To be clear I think it's fine right now to back tech for healing. It's more pricey than other factions if all you want is medics, but you get some advantages and it's close enough. But add on the proposed 100mp and 15 more fuel and a bunch more research time and things start to look extortionate. 400mp 55 fuel and 3 research/build delays is just not cool and not close to how faction was designed, if that was your pathetic defense above.
I do play other factions with easier access to medics. Each faction has an advantage and disadvantage to their medic deployment, so you can't blame the okw specific advantages for the extra costs.
