I think Stuka is balanced. The rockets hit where it needs to and 100 fuel for OKW is a bit too much mid game to compensate Stuka's effectiveness.
That is true. I do not agree with the price being too much and its current timing. It should be as cheap as the Katusha and become only available last base. Currently in many situations, who would ever use a Walking Stuka for the way it currently performs in comparison. 100 fuel is insane on top of everything else.
Switch Walking Stuka maybe in Mechanized base with some other unit. I hardly use it since I consider it unreliable. I would rather use Katusha and Panzerwerfer since they are better and cheaper. Even a Land Mattress is way better and cheaper. As I have stated, it seems to be the only mobile arty vehcile to get streaks of NO kills. It highly likely due to its loud noise, high predictability , slowest projectile. I dont agree with its price and timing, change that.
It is even terrible against structures, which both Katusha and Panzerwerfer are way better at doing.
