sigil of the night
It depends. If any raids occur under night conditions, they will remain popular.
They don’t Ayrilana, it has already been confirmed.

Ah. I haven’t read that post yet. None of the builds relied on sigil of night so I don’t see them changing because of it. However, they will change based on the specific raid most likely.
My guess is that Sigil of Air (in conjunction with Force, of course) will take the place of Night for zerk builds since frailty won’t be needed with a 10 person group.
