it's even worst when it's dropped on AT guns, cause it takes some seconds for an AT gun to pack and move and it (allies AT gun) doesn't also have a retreat ability, so if the Stuka dive bomb is dropped on it u're dead most of the times even if u immediately notice and try to move away,
with how big the area of effect of the stuka dive bomb is
BUT all in all, not sure if I agree with calling it OP or not cause it's a part of Ost faction. for example, if you gave one ability or unit to another faction it could be OP while in another faction it could be balanced, same for different docs, and all the docs which have this ability, I don't call them OP.
even though it was bullshit OP in the past when the fuel to muni convert was still possible and how you could unfairly spam them with not much effort.
