Are they even useful and/or up to par with any of the other casting powers especially in higher content? I have a feeling FB could do a lot more damage if it didn't have the problem of being blocked constantly (performing the SC in front of a teammate will void every single hit) and having to be up close for maximum damage. I'm still gonna scream and ask for the Wings of Phoenix type of supercharge, where fire's might and crits shoot up 20% while having unlimited power for a small amount of time.
With the current state of Fire's AM, neither supercharge is really useful. They result in a slight loss in dps compared to an all-AM rotation. When the weapon damage pass occurs and WM (suposedly) becomes a viable option again, then Volcanic Calamity would be the preferred supercharge to run as it would get the initial crit bonus that Fireball Barrage would lack.
WB into Volcanic Calamity works well, however you're loosing out on damage since it only crits at roughly 15k with another smaller DoT which to be frank is less than ideal comparing to Grand Summoning.
