The dialogues are fine as they are. If you don't want to read them, don't. If you have troubles understanding them, work on your English skills.

I'm neither a native English speaker nor am I studying English at the college/university.
So why am I not having problems understanding the dialogues (or monologues)? Except maybe the Limsan ones?

Too many people just blank out the moment they stumble upon an uncommon word (instead of looking it up for example) and just end up skipping the whole text, then complaining the text is too hard to understand.
