It makes zero sense for the PLD class to have three different skills for AoE

I imagine one of them is going in ShB to be honest.

I hope it's Eclipse personally, and Flash upgrades in to a magic lightning AoE.

Hmmm... to me that's a tough one, I like the look of Eclipse but I agree that it would potentially be prudent to consolidate the two abilities into one functionally.

If I were to do that I would just remove Eclipse and provide PLD with a trait that upgrades Flash to give it some damage as well.
I would keep the holy light theme to it and call it White Light as a little nod to the localization in FFII(FFIV) on SNES in the US where they changed the name of Holy to White.
Visually it would keep the visual effects of Flash but add to it where little white circular motes of light crackle in the area of effect, sort of like how some fireworks look. The little circular white motes would be an homage to the visual representation of the Holy spell in early FF games.
