Halve splash damage. That'll make infantry happy. Bring their dps up to the rotary, but at 1/2 the rotary's range, and maybe 75% of the rotary's velocity. That would make them a decent dogfighting option, while being half as good at farming infantry, but still considerably better than AA noseguns. I'd be happy because I wouldn't have to run Coyotes when doing A2G. The PPA would need the most help in the AA department. I suggest upping the velocity, halving damage, doubling rpm, and doubling magazine and ammo capacity.
