You say Sturms are only for repairing late-game, but why not attacking AND repairing? USF makes it work with REs. Goodness knows I've been making it work if I treat them like squishy shock troops w/o smoke nades. And if you don't have enough dedicated sturms for reps, just make more! You agree that OKW has manpower float, right?
OKW MP float is largely absent in lower game modes, and generally happens because everyone else is spending MP on tanks while your spending it on...spamming more infantry
Also USF makes it work because all their crews can repair, and RE's are 160 MP not 320. Having more than 1 Sturm is generally the meta now and you will be rotating them back and forth repairing and attacking.
Iv still have yet to see a substantive argument against buffing Volks that actually uses numbers instead of vague feelings.
I actually agree, they are pretty bad at vet0 and should get +20% acc on vet 0 while changing both vet2 and vet4 bonus from +30% to +20% not to make them any stronger past vet3. That way they will be able to bleed allied infantry better on long and mid range. Also there are two t0 units that were ment to stop incoming allied forces: sturms and kubel, so they dont need more buffs.
You can't spam Kubels or Sturms, getting more than any one of those to early on can be extremely risky. It also seems kinda silly you need to put a lot more effort into fighting the enemy than your opponent does.
What Volks need for their Vet isn't more at Vet 0, it's for them to just have a cost increase with performance increase (say 255 MP for a middleground between Rifles and Grens like IS?) and or a cover bonus similar to IS so they won't be blobbed.
