I think OKW probably needs a huge batch of simultaneous changes to accommodate 100% munitions income and an ISG nerf, but I think both of those things would make the game more fun for both sides.
Remove shrecks on volks, give them pfaust and put OkW at 100% muni income.
Think of all the fun stuff you can do with mines, nades and commander abilities.
And it would also indirectly buff the raketten, since volks will now reliably snare enemy vehicle's.
But i doubt this will ever happen.
