There is a precedent for that, I mean they nerfed missiles and they've been completely useless ever since :/ but I always hope they will do the right thing!
I think fd nerf too far on purpose then use the comparative nerf rebuff volume of howling to interpolate. However they only seem to interpolate once per update.
Seeing as no one has thrown out any numbers yet i'm saying turn lowestspeed turn rate to 15 seconds and mid to 10.2. Bear in mind this will be about 10-16% quicjdr due to large thrusters to mass. And it will still turn phenomenally well, it just won't be outpitching in a stall what most ships manage in the blue zone.
