My Catharsis in FFXIV

While their culture may be more “inclusive”

There are many wonderful things about the Japanese culture - IRL and online.
'Inclusive' is not something that would be top of my list of adjectives where non-Japanese (or at the very least having a very workable knowledge of the language) are concerned.

As you imply - the if the OP is struggling to acclimate their native server - I can't see how they will fair any better on a JP one - if tackling any sort organized group content.
