Skill Name Change - Black Mage

[Sairys]

This is actually incorrect. The first FF game (that was translated into English anyway) to feature the 'ra/ga/ja' suffixes for spell names was FFVIII - FFI, IV, VI and VII all used "spell name + number denoting spell strength". And FFXI used both, leading to some silly names like "Thundaga V". It's no big deal to me.

It's clear SE will not be changing this, as Ferne made his choice, as Rongway said.

You're actually both correct in a way.

FFVIII was the first English game to actually translate the suffixes with them being present since the original in Japanese. (The only exception being FFII because of it's ability levelling system.)
However, looking across the ability name tables you can also see that, after FFVIII used the suffixes, the remakes of the earlier games have all used them instead of the number system. So it's entirely plausible for someone to have played every game in the series with the suffixes present if they've played the versions of them released after around 1999 or 2000.
