In 1v1, you're basically not allowed to use stock mediums against OKW. Its already difficult to use stock mediums vs OKW P4, however, the raketens have the RoF of the USF at gun and basically the penetration of a pak (only 10 less) and now have almost the same range with an extra crewman and retreat. There's little u can do to counter a raketen. I'd say it's at least as survivable as the Zis now. I think a slight pen nerf is in order
M1 fires at least 80% faster. I'm not sure what you're smoking dude. It's not even somewhat close.
The strength of the raketen is that it can creep forward and be used more aggressively than other AT guns due to retreat ability. The downside is that they can very easily be stolen if decrewed while other AT guns just get destroyed or might even still remain there when decrewed.
Rak crewmen die many times faster due to lack of gun shield + shorter range + clumping because of the smaller gun, so raks bleed a ton more manpower than other AT guns and are far more prone to being wiped.
The rak also has a slow ass projectile which results in it not being able to score scatter-collision hits like other AT guns can. The rak has a low firing angle which makes it the worst AT gun to use whenever there's an ant hill or a small twig.
Of all the cancerous things in OKW - G43 blobs, Falls, OKW Tiger with artillery, you literally had to pick a non-factor to discuss.
The rak basically made a transition from "useless except for cheese" to a decent AT gun. I guess people were too spoilt and too used to OKW not having an AT gun, and now that it actually fulfills that role people are shocked. 70% of my games this patch have been with Allies and raketens haven't been an issue or concern in a single one of them.
