Again. What you're suggesting is not really early game. The problem is that OKW neither has good support weapons to control mass enemy infantry (Can't counter support weapon spam effectively either. See: maxims) nor good abilities to punish blobbing early game. Scavenge doctrine being the closest to fulfilling that role.
This all leads to OKW being a shitty one dimensional faction (not necessarily underpowered). Having to either blob harder than whatever it's playing against or locking your fuel and hoping that the enemy isn't good enough to push you into your base until you get better tech.
Basically, you wont accept any solution that isnt an mg even if this one comes in 5-7 minutes were you can start seeing blobs and only if the enemy player goes hard on it
