After reading the forums for a bit I think the best thing to do with Ost is to remove it from the game, that would cut back like 70% of balance threads and complaining.
Then we can get rid of USF for another 20%.
Remove all weapons from Axis factions. This should lead to somewhat balanced win rates at about 50%, though Axis OP so they’ll win more.
Honestly, I'd do something like cut the Tiger's armour down to 280, its health down to 960, give its main gun anti-infantry performance like the Comet, and cut it to 200 FU. Maybe even raise the cap from one on the field to two.
Why stop there? I believe this should also entail a reduction to 185 fuel, 18 population and further nerfs to reload speed.
