I just wanna doublecheck something (BLM)

The lv94 BLM is right but to kick you for it is just LOL. Report him. Keep in mind that the fact that fire 1 keeps you in Astral Fire longer is not that a big of a factor, its a very minor one in fact due to the way BLMs work. I'm too tired to explain everything so just parse it, have one BLM do fire 1 and one do fire 2. The result is even more apparent one you get Flare. Why? Too tired to explain, parse it.

This might sound a little dumb but I just follow a simple rule of thumb for low level dungeons. If they are a Warrior, feel free to AoE all the time because with Overpower they should be fine to hold hate on multiple enemies. If its a Paladin I tend to be a little more cautious and ask if they can hold an AoE rotation before we start or see if they are marking targets.

In terms of numbers, its really only viable in low level dungeons to AoE at 4 or more enemies otherwise single target is better for maximum DPS. In the endgame you definitely need to AoE a lot more to speed things up.
