Most people can ignore APA rules and just wing it. E.g. English comma is more of a "there's a pause" in most communication.
Don't know about Bulgarian, but Russian punctuation is notoriously horrendously complicated. I still remember a dictation [1] which had a sentence that had a comma after nearly every word. (And this last sentence would have three)
> English spelling is better than, let's say, Greek or French.
Can't speak for Greek, but IIRC in French a collection of letters usually conforms to a rule. "eu" or "ou" will rarely represent different sounds.
Whereas one of the famous spellings of "fish" in English is "ghoti": https://en.wikipedia.org/wiki/Ghoti?wprov=sfti1
