I've been dropping nukes on GEO with no bubble or other support for magic on Normal and Difficult. 9k fire III's 13k fire V's and 70k+ MBs that I had to chill on so I didn't rip hate from NINs. It's not melee damage but seems fine to me. Honestly I'm with Nyarlko. It was really annoying repeatedly but doing it once with the ability to still land some decent ranged and magic damage is fine with me personally.
