Hello healers, I have one question about Selene's usage in FCoB.

When my static were at T11, they asked me to put Selene away because her Skill Speed buff was too much for our DPS, Monk specifically. After a while I realised that it must be due to TP draining and the Bard having to play Paeon more frequently to compensate.

However, what I want to know is has anyone actually calculated the impact it would have on overall party DPS? Or does anyone have a more in-depth reason for why Fey Light should not be used?
While I can understand the Skill Speed buff will alter the way the Bard has to play, it still doesn't seem right that such a significant buff would actually cause problems rather than more DPS output. And surely it's still right to use Selene when farming FCoB?

(I saw a similar thread to this in the DPS section, but they were talking about dungeons. This thread is specifically for FCoB, as I see no reason to not use Selene in any other content.)
