I never recalled saying the english one isn't done. But if the leaker is chinese like last time, he/she might not have access to the english website. Just the chinese and good old fashioned google translate.
Sorry but a FFXIV job has a lot more stuff to them than one wow spec. Between the exclusive weapon type, armor job questline, cutscenes and solo duties...yeah. Plus each of them have enough mechanics to not be super boring. Compare ninja to any of the WoW Rogue specs.
