Ack isnt a problem at all. Its completely predictable. If you think it is THAT dangerous, do not fly in it.
I do not like that it works off of percentages, as in no matter what I do, there is still a chance I will get hit. Unlike field guns that are somewhat possible to adapt to and avoid.

Are farther away from the source
Flying at a higher rate of speed
Are maneuvering
