Why is Mumyo Shoha translated to Shoha II on the English Client?

[Mimilu]

Probably on the same logic as things like Fire II being the AOE equivalent of Fire. It's pretty common among the mage classes.

High Fire/Blizzard II confused me so much when I got them because I was like "Where's High Fire/Blizzard I? Did I somehow skip something?"
Nope, XIV's English skill naming convention has just gotten weird and convoluted over the years. ꉂ (´∀｀)ʱªʱªʱª
I've seen a few newbies get confused by this and think that Fire II was an upgrade to Fire, so they should spam that, regardless of if the situation is single-target or AoE.
Hell, just look at WHM, Glare > Glare III, like we're going to get an AoE Glare II. No clue why Holy III is a thing either. ( ಡ艸ಡ)

Japanese and German have the traditional FF suffixes (Spell > Spella > Spellga > Spellja (JP) or Spellka (DE)), while French adds a word in front of their spell upgrades (Spell > Extra Spell > Méga Spell > Giga Spell).
