Eh, I'm sure calling it Blizzara wouldn't make it THAT confusing, it's still an AoE version of Blizzard just like how Fira would be an AoE version of Fire.
Hell, if you want it to be consistent with things that are already in XIV, Amon in Syrcus Tower has an attack called Blizzaga Forte which operates just like a bigger version of Blizzard 2, so you could always go with that minus the "Forte".
