Does selecting "Yaw into roll" in the bindings help?
I wouldn't advise it, I guess it depends on your flying style. Normally I fly with a full HOTAS/Pedal setup, very easy for interdictions, my legs are doing most of the work.
My whole setup is in boxes due to moving house, been flying KB/M (got interdicted in a T9, 7x times in a row due to stacking) I had Yaw into roll enabled, survived all interdictions but it was difficult. Yaw & Roll needs to be completely separate imo
Off topic: They should really sort out the interdictions due to stacking, the whole thing is broken, it was comical having so many chain interdictions. Clearly not by design, just a result 2 NPC's being sent per cargo mission. Make a trade run more difficult for those running multiple cargo loads, but get rid of the spam interdictions.
