Next New Jobs after Dawntrail are likely Aiming/Striking

[Halivel]

I wish once in awhile they would do three. This isn't 2.0, and 3.0 anymore. I believe if they really wanted to put the resources for it, they could find a way to do three jobs again.

They did three for 3.0 and explicitly said that they don't want to go through this again. The team was overworked so much that I vaguely remember Yoshida mentioning that they all went on a month long vacation after 3.0 release (which is generally unheard of for Japan). And "this isn't 2.0 or 3.0 anymore" is more so the reason why it would be a bad idea, because with higher amount of jobs it's getting harder to create new jobs and balance both new and old jobs around each other, not easier.

Sooooo yeah... most likely not happening, as DevTeam already been there. If nothing else, at some point we're likely to see the shift towards 1 job per expansion.

Creating new teams dedicated to balancing not only won't necessarily fix it - it can make things worse because in-department miscommunication is a thing and happens all the time as it is even within a single team, let alone if there's more than one working on the same thing. It's not all as easy as "just add more people" (I wish it was that easy as a developer, but yeah, nope).
