Not sure if this is a bug, but my POD Neon with adaptability kept using mind-bending against Angelo instead of thunderstorm which would have dealt way more damage, especially given Angelo's high MDEF. I will not be using my Neon to challenge Angelo until they fix the AI on this.
I have tried different combinations of Drac, Ignightmare, Behemoth, Scythe, Neon, Rhor, Smiter, and Champ against Angelo, and it seems that Scythe's martyrdom seems to do the most damage.
The AI for boss raids is not great. I had two Meniss attack Angelo, and rather than using cunning, they used shadow swipe and shadow storm respectively in every raid. Likewise, my Chunky is equipped with cunning, but it keeps using chill instead.
