Brimstone look at the abbreviations for class's in your post. Doragoon, Paradin. XD
Wow, almost 35 years and I never noticed that! Gungnir is also misspelled, but many languages have less correct translation to english (I think there are many norse, greek, arabic words that have multiple 'correct' translations.)
Square (and subsequent companies) has always been below par.
One of the earliest works in the entire fantasy genre (Pilgrims Progress by John Bunyan) has some perpetually creative spellings throughout the entire work. Of course it was written at a time when maybe 10% (being generous I think) of population could read and no dictionaries existed, but spelling the same word more than 1 way on the same page is a bit...I dunno.
