I think it more or less works for every weapon except for like... DB, bow, and gunlance.
G Fulgur 2 piece opens up Maximum Might to weapons that wouldn't otherwise consider the skill, but DB and Bow are still too stamina heavy to make use of it. And Gunlance doesn't give a shit about crit so they're just rocking 4 piece Odo for Burst damage/uptime
