I wouldn't bet on that.

Since it's in the class role, Esuna as been even more useless that it already was. There's just Exdeath loldoom to annoy people for free but it outside this, nothing. Certainly because they noticed part way then didn't handle the thing properly and they couldn't make something optionnal then force for player to use it just to justify its existence. Hence why exeath only casts its doom once at the start of the fight.

Cross-skill should be about playstyle and situationnal gimmicks. Things like largess, E4E, surecast, cleric stance and rescue fit perfectly. Protect, esuna, lucid dream, break and swiftcast are either mandatory or useless. And because of that, they can't play arround it, wich end with most relevant content bypassing surecast most of the time.

I wouldn't be surprise it they were changed in a future patch.
