Like the Centaur?
The Ostwind is seriously lacking in performance. My buddy used it some days ago to great effect but even at vet 3 it had serious problems wiping squads. Something the Centaur would have done easily. Imo it needs to have better accuracy on the move so it can chase down infantry.

The linked part (until 29:40) shows its biggest problem. It can't hit while moving. And even the accuracy while standing leaves room for improvements.
Please patch your game.
You're talking about Centaur from last year.
Current Centaur is better then ostwind exclusively at taking planes down.
