I was also wondering this myself. I won't complain about getting new jobs every expansion, but that is more work on them (and more time spent leveling yet another two jobs to max). I think there might be some holes they can fill here or there, but eventually, I'd guess they'd say enough is enough!

Yeah I have this feeling that 7.0 will be the last with 2. On the plus side that would hopefully mean more time can be given to developing side content, or maybe they would just have them focus on job balancing/reworks.

I feel like this is the main reason they've been homogenizing tanks/healers and unifying burst timers. They feel compelled to add multiple new jobs every expansion, and this makes it much simpler to design and balance them. That said, I'd prefer seeing few unique jobs over many samey ones.

Maybe I was just imagining it, or was there some talk of 7.0 giving a new starting point in the story for players? If that is the case that could maybe play into needing less leveling for jobs.
