mf and strong box?

just curious, how much does mf affect strongbox farming? is it worth it to switch to sub tier mf gear at all?

Nah mf gear doesn't apply to strongboxes only to the monsters killed from strongbox.

-Like chests, increased Item Quantity from gear do not affect the number of items dropped from a strongbox. However, Item Quantity bonuses from area modifiers and the number of players in a party do increase the number of items dropped from most strongboxes.[6] The sole exception is the Cartographer's Strongbox, where the number of players does not increase the number of maps dropped.
