SCH, Eos or Selene?

[Zaresin]

No good math would have have Fey Wind do a 1.5% increase in party DPS. It's much less.

Considering people with more knowledge and experience compared to your few months experience have crunched the numbers on numerous posts and sites about this, you might want to back up your post with actual data.

To the OP. Which fairy you use is situational. If you are not up to par or just not that great of healer, then eos will be your go to fairy. If you are a competent healer then Selene will be the fairy to use. Any kind of raid wide increase to damage output like Selene's remade buff does is less healing you will have to do overall. If something dies faster, less healing you should need to do over a course of a fight.

I will say this, eos is a crutch for bad healers a lot of the time. Whether it is gear related or skill related is not the problem as both are fixable. Having s potency increase to compensate for your short comings is a definition of a crutch.
