my experience with the jp community in ffxiv has been positive. i can read kanji so i can understand the gist of what the jps are asking for when i see their grind pt shouts. i always send the shouter a tell in full auto-translation asking if i could join the party, including my battle class and level and a smiley face. never hurts to be extra nice when you're communicating with them. during the parties, the leader, knowing that i am the only english speaker in the party, would take extra patience to type out important commands in auto-translate. the only time i had trouble understanding them was when i made the mistake of using google translate to say "hello" and "thank you for inviting me" in japanese...they thought i was jp so it made the communications later much harder to understand lol. i also always remember to say thank you and the polite farewell phrases and bow after the party is over. extra courtesies are always encouraged when playing together with jps.

also, i have never seen any shouts on trabia with "jp only." maybe i'm just lucky.
