As already noted it is not like OKW have anything else, and their units are suppossed to be expensive but effective or cheap and well vetted.
Stuka is not overpowered at all. As he said, OKW is meant to have units that are EFFECTIVE but EXPENSIVE.
Kat and Pwerf could use a slight buff so that even when firing at blobs, every rocket doesn't spread out and miss but stuka is pretty fine where it is. The few times i've tried to use a kat against OKW hasn't really done much for me but I may need some practice.
To those complaining about getting squad wiped on retreat, that's not the stukas fault, you played someone smart enough to drop rockets on your retreat path while you're there. Would you say that if I was using a preist to do that as well? How about don't retreat when you hear the rockets coming if they are landing on your retreat path, just advance forward or move to the left/right.
Secondly, Stuka has a distinct sound when firing, that can be heard and give you just enough time to move units. Whenever I hear that thing fire in a game, I move my units. Most importantly, I move my AT guns/MGs.
Thirdly, its an artillery piece that launched HE rockets. It's gonna fuck shit up and decrew weapons, that's its design and it's really fucking good at it. All that means is not to just place a static support weapon somewhere and think that area is locked down. Keep moving. Change positions.
390 + 100 fuel is a big deal to lose. Flank the stuka. It's not hard, in most of my 2v2 games I can get some infy behind enemy lines and deal with it. One AT nade and shock troops and the thing is dead is no time. When I see or hear a stuka for the first time on a map, especially early game, I instantly try to sneak around and hunt that thing down. The longer you wait the deadlier it will become.
If they go for the quick stuka, that's fuel not going to any other tanks or vehicles as well as the fact that the only AT capabilities that that player has is the raketenwerfer and the puma, both of which can easily be killed by combined arms attack.
TL;DR Don't line up your shit.
