I already showed you 2 high-level replays with huge fuel float for OKW.
You can't use that game as evidence that OKW somehow is OP due to resourcing and conversion.
Giap and Gaddafi not only held their fuel for the entirety of the 1 hour match, they also contested and cut off ours. The only reason Giap could afford those many tanks was because of their map control, especially the munitions, allowing him to get a decent amount of income at a severe cost of him barely throwing nades, upgrading units, and using ablities.
