comparing Aero and Stone nukes on Moogles vs. Amal'jaa, I have roughly even numbers between Aero (~300ish dmg) and Stone (~340ish dmg). However, at the Amal'jaa stronghold, my Aero was hitting for only 400ish, while my Stone was hitting for 800ish.

This leads me to believe that either Amal'jaa are now either weak to Earth Magic, or resistant to Wind Magic. The reason I can't really tell is that I'm not sure how much of an effect the level difference between Moogle boss mobs and Lv52 Amal'jaa has on my nuke damage.

Either way, Amal'jaa were weak to wind previously, as they are Fire elemental. It would appear that Fire could be weak to Earth now? (More testing obviously required)
