Yata isn't a raid, it's an advent and it's not like you need to use an element strong to the event to clear it.

Attack down debuffs is one of the best debuffs in the game, with only 2 event eidolons so far with it, Yatagarasu being one and Jormungand being the other, it should be a priority for anyone.

Though considering your roster, I would assume you're new, so not much you can do if you can't clear her.
