Set bonus is the old 15% crit & 8 less ammo cost on HiB
Haven't run enough ops since 2.0 to alter to 30% crit or the full new set bonus.
Not really following you on validating the parse but I can provide multiple consistent parses.
Technically Assault is hitting harder than Gunnery but you won't know it til you're in a raid.
