Not to go too off topic but Final Fantasy VII had some really awesome Blue Magic abilities yes, learning Beta early from the snake and using it to nuke literally anything was amazing, because it was a mushroom cloud when casting it and the Pandora's Box spell I think it was called that you get late game, great ability.
FFXIV loves its fanservice, right? I'll take Blue Mage if it had some FFVII spells to learn along the way, very underrated abilities. Because most only remember Blue Magic from V or XI. (Mostly talking about game exclusive abilities not shared ones =p)
