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

[Telkira]

The point here is: names are an interface. If the suffixes don't encode any meaning--that is if you can't look at Spell and Spellra and determine what -ra means other than "Spellra is different from Spell"--then they are no more meaningful than just numbering the spells, and if it comes down to a difference between invented numbering via suffixes and just using plain Arabic or Roman numbering, then it is objectively more accessible to a wider player base to use the plain Arabic or Roman numbering because they already know the difference between 1, 2, 3, and 4 or I, II, III, and IV without having to learn what the invented numbers ---, -ra, -ga, -ja mean.

I personally prefer suffixes too, from the perspective of a lifelong FF player. However, those suffixes need to be meaningful and systematic, and implementing a meaningful suffix system at this point is a non-starter. The names of spells that we've already been using for ten years would have to change and that would just make the already-out-of-date old internet info even worse. Because so many players are bad at restricting search results to the past year or six months, it would confuse a lot of people even more because the old guides will talk about Thunder -> Thunder III and Thunder II -> Thunder IV vs new guides talking about Thunder -> Thunder II and Thundaga -> Thundaga II. Fire, Fire II, Fire III, Fire IV, High Fire II vs Fire, Firaga, Fire II, Fire III, Firaga II. Etc.

Had SE simply stuck with the suffix-based convention, we wouldn't be having this conversation right now, and people would be less confused since no expectations would be had, especially for newer players who might view the use of numbers or numerals as linear power upgrades, and not as different skills.

If they do decide to give players a secondary English language (EN-JP) option to play the game with, then using the conventional naming conventions would be a neat treat.
