I've gone over some various posts on the forums here but haven't quite managed to find anything properly definitive on the subject of Sic and Obey.

Eos' abilities are far too useful, and have far too long cooldowns to let her control, but am I a terrible person or worse, a bad healer, for bringing Selene out and leaving her alone? Is the flawlessly precise uptime worth not having direct control over Silence? Even further, is it worth losing Whispering Dawn, Fey Covenant, and Fey Illumination in order to keep up the 30% haste effects? I certainly like the last two of those abilities, but I find it very difficult to fit them into encounters efficiently, whereas Fey Glow/Light is a much simpler thing to use.

In short, how does I Faeries, kthx?
