[dev1206] Class Reforms & Action Lists

[AmyRae]

^^^

Water-element spells started out solely with the Leviathan summon. After that, FF5 started the trend of Blue Magic getting the elements that Black Magic didn't (in this case, Water through Aqualung/Aqua Rake and Wind through the Aero line). It was Blue Magic in FF6 and 7, too. 8 on made it an actual Black Magic spell.

Nah, your history glosses over a lot of water-based attacks. You'd probably consider it the domain of Geomancers and Summoners before you would Blue Mages. Prior to FF8, water was in 6 Geomancy spells, 5 summons, and only 3 Blue magic spells.
