Hetzer has smaller target size and better armor than Ostwind. We need nerf its armor if we move this unit out of Panzer Authorization lock.
We would if it did more than zero damage to light vehicles.
Stuart versus Flame Hetzer, Flame Hetzer loses.
Plus, have you all people complaining about Hetzer have even used it in last 12 months? Its perfectly fine for performance where it is, it doesn't matter it can't damage vehicles, that's how AI units work, it can easily 1v1 ATG and will murder all infantry that isn't supported by a med tank at least.
I'm not saying it should damage vehicles. It's a flame tank. It shouldn't damage vehicles.
I'm saying
because it can't damage vehicles it's foolish to treat it like the Ostwind, which kills lights.
The Flame Hetzer's a good unit, but its position in the tech tree means it's rarely a viable pick. By the time you can build it you need your own medium tanks out.
It's a bit like the Soviet M5. That's also a good unit, but in Soviet T3 it's forever under the T-70's shadow.
