As much as I have some of the worst result with RNG (case in point being last night's map runs), cases like this is why I'm glad my FC always do FFA for maps. I never knew about rules like this until I once joined a PF map party that was called out in a hunt linkshell. I don't mind it if the party leader wants to have such a rule, and certainly if you've agreed to the rule by staying in the party, then you should abide by the rule, but FFA just seems a more stress free environment with less expectations on other people.

Anyways, I hope you'll find a more suitable FC soon (if not already by the time of this post).

EDIT: I was wondering if lootmaster would've prevented this situation, but then again, the lootmaster could've been the problem, oh well.
