Your biggest fears for 4.0

If they didn't do anything different or game-changing at all even though they have triple the budget now.
It's been about 3 years now since ARR, 4 when Stormblood is around. It's time for big changes.

Except the MMO market is volatile, and exceptionally difficult to achieve success in. They may not have the luxury to try wild experimentation; I imagine there's quite a lot of pressure from those above to "not fix what ain't broke" (and they'd need hard numbers to demonstrate "broke", not the clamours of the online masses), and any major changes they make would have to be just as possible of engaging the same number of people to be worth the investment.

By change I meant improvements, not really fixing something that's not broken.
ARR was a huge success even though it still felt half-baked. It's still half-baked even now and still successful, but there has been a decline. They should make improvements at this point.
