I honestly would not call this thread a balance discussion. In the first post you summarized your feelings playing Oberkommando. Not really a discussion where you point out that this unit needs a buff or that one.
I slightly wonder, to be honest, why you left T2 (Medic Truck) out of the equation as the leIG is a great tool combined with Volks. Volks do not deal much damage, they have good survivability and lategame scaling due to a Schreck. In the first few minutes they can still compete vs opposing infantry, but once BARs or PPSh41 hit, they can only do much with nades. Yet they can still reveal and be a meatshield for damage dealers like Fallschirms, Obers or the leIG.
The other posts are usually either off topic, or ones by VetLolCake are an agreement. Nowhere you really state any balance changes. The only thing I see is you asking for design changes (more allround units, ...), but that's not a balance but a design discussion. Jagdpanzer, leIG and mines.
PS: Against Flak HT rushes you can try to wire off on quite a few maps. Kholodny ferma for example has lots of points that can easily be wired off to prevent it from roaming so freely.
Well i left T2 out as it is a given that you would build this tier as you need the healing. Yes you are correct the leIG is a great tool, but its a support unit that costs a bomb. If you make one of these u are left with no capping power. I actually normally build this unit most games as it soft counters vehicles and "can" be good against hordes of infantry.
However volks will not keep riflemen armed with 1919's in vision for long as they will just melt. Also you must have your leIG protected at all times coz it is the last thing you want stolen from you, therefore losing more capping power.
Balance and design are fairly similar things TBH. If volks are designed to fight at long range then they should have decent DPS at long range etc etc. Design is how balance is created.
I never knew that WIRE stopped a flak.........
