The ST44 upgrade is problematic. It creates a squad that can fight at all ranges. This has lead to number of changes like:
The nerf of the 5 vet bonuses
The redesigning of USF tech tree
The terrible state of Ostheer
That's a nice theory you've got there, but its completely false.
Vet5 nerf is a direct result of redesigning OKW economy, so they no longer had an excuse to rely on powerful infantry to carry them through lesser armor presence.
You have a dev comment on why USF tech tree was redesigned, I gave you the quote, so you're 100% aware you're lying here.
"Terrible state of ost" is literally 3 units needing a little bit of love.
