How is anyone fine with the 4-month patch delivery schedule?

But hey, I heard they were hiring and have even gone as far as to advertise this on their PLL, several times. So by all means apply.

For French and German translators, specifically, yes.
Probably not going to make much of a difference, if any, in the content development of this game. And if it does, then there's something very wrong.

But on the other hand, I've seen first-hand what this looks like under their current philosophy with Ishgard Restoration.. Hurrah for unreasonable grinds.

I'd say that the only reason it became unreasonable is because it was a time-gated competitive event. Note, however, that the replay value of Ishgard Restoration is now, for the most part, gone, now that the restoration is complete.

Square Enix... does not revolve solely around the Final Fantasy XIV franchise

You're right, they revolve mostly around Final Fantasy VII.
