Phaenna... Only two red alerts? No ARM red alert missions?

[Fynlar]

Patience; it isn't all there yet. Zone progression is needed.

Like the last area that also only started with 2, I assume that the more we build the area and the more we'll unlock other red alerts, and since SE likes formulaic, this is probably going to go from 2 to 6 total at the end like for Ardorum.

Actually, Sinus Ardorum started with 4 RA variants, with a 5th and 6th gradually unlocked.

I do think that Phaenna will also eventually end up with 6 though, based on the amount of critical missions still unavailable.
