Ost has problems. Your post does not address their core issues however.
- Grens in T0 would negate a minimal advantage the SU has over them. T2 rush would be also too common that way, not that they have any groundbreaking game changer in that tier, but still. Giving them a close range nade is against their design and would make them too versatile.
- Any explanation regarding swapping a decent MG with the shittiest MH in gaem?
- The GrW is 100 times better than that unstable, inaccurate piece of garbage.
- 2 Shrecks are alright. It is a choice between dedicated powerful AI or dedicated powerful AT.
- Both the panther and ostwind need some kinds of improvements, not sure if your suggestion address their shortcomings.
- Double nondoctorinal tigers is a tad silly. Though seeing as how we face comet blobs, your suggestion isn't that far fetched. And with your proposed change to other factions it could be somewhat balanced.
- Those types of trenches are a design level advantage for the UKF. Let's not chnage it.
