Is Selene all that?

[Cynfael]

Ya that's why I use eos. I'd rather play it safe than get a minuscule decrease in how long a fight takes. No matter how overkill eos may be it still has a chance of being very useful whereas selene will always be underwhelming unless you really need the aoe esuna.

Edit: I guess selene could be amazing if the boss is enraging and a few seconds would've made a difference.

Unfortunately the reverse is usually true; Eos brings nothing but more healing and magic mitigation, which is useless if you are perfectly fine without it. More DPS, even if marginal, is always preferred.

When I first started playing, I was of the same opinion about Eos vs. Selene, but I eventually realized why many players favored the latter for most situations.
