Damn, I must have missed the patch that allowed panzerwerfer, katyusha and calliope to pinpoint-accurately wipe pakhowies and mortars on max range in the fog of war when they have to finish their firing animation before packing up... same for HMGs and AT guns ofc.
You get to whipe one squad accurately ( assuming it isn't a soviet 6 man squad ... and even 4 man squads can sometimes survive ). If you get to kill more, then the enemy didn't space them out enough , didn't pay attention and you also got lucky with RNG. Also since you mentioned fog of war. With Stuka you need to know exactly where the enemy put his troops ( with mortars this is possible, but not with MGs or AT guns ) . With Werfer you can just take a crude guess . Sure, you might not whipe the entire squad when its on longer ranges, but at least you get some kills ( also team weapon Squad whipes are still completely possible with Werfer on Max Range ) . With Stuka you get 0 when you don't aim it exactly where the AT gun / MG is.
Or which allowed them to arrive at the 7 minute mark like the stuka does.
Basically noone gets Stuka to foot in 1 vs 1 at the 7 minute mark. Even in 2 vs 2 you don't want to do this as OKW.
In fact it usually even arrives later than the Panzerwerfer and the Katjuscha since most OKW players tend to go T1 in 1 vs 1 and also in 2 vs 2. And even if you go Mech. Company into Panzer 4 it will still come later than a Katjuscha that arrives after the first T 34 and only about 1 minute earlier than a Katjuscha that arrives after the second T34
