the 0cp extra salvage is way too unbalanced early game, you can get 5 min luchs with this thing
Luchs costs 50 Fuel + 80 Fuel (Flak HQ) + 40 Fuel (Medic or the other HQ) = 170 Fuel.
170 / 5 = 34 fuel per minute.
I don't think that you can get 34 fuel without conversion as OKW even if you own every single sector on the map. Remember the OKW fuel penalty.
What wrecks do you want to salvage in the first 5 minutes?
