Despite being off topic, and I remember mentioning this somewhere before but I don't remember, Def down can be useful. There Def down, Def ignore, and Weaken. A lot of harder bosses are immune to Weaken, and bosses can remove Buffs in a few cases. So in those cases, Def down is pretty useful, but I think that Ignore has better general use overall
