Dear Devs fix the spells names!

FFXI actually used both, leading to ridiculously convoluted spell titles like Firaga IV.

As ridiculous as it is, it was enough to teach us that Fire was single target, Fira was AoE from the caster and Firaga was AoE around the target. Firaja (which came out before the elemental -ara spells) was also AoE around the target, but it also gave the caster a 5% fire (elemental) buff that increased by 5% after every successful cast.
