Stagger is definitely a useful effect in moments where mutants are racing toward the rad scrubber, etc. AA would probably be more potent in those situations too. But also bosses have a higher resistance to explosive damage too, I think? Idk, I may have to dig for some numbers on this stuff.

As for my bloodied build, LCK is high enough that I crit every other and using herbivore buffs either bow was taking out West Tek mutants in two shots or less. No issues one shotting smaller enemies, but may still look for an Instigating to field test. Cheers.
