Same. I was under this presumption from the beginning, too.
Driving the ships themselves would be dope but I have no idea how that'd even be coded/developed/work tbh.
This expansion is built around Garrisons. No one should really expect a divergence from a focus on their content; they're one of the expansion's primary features.
If you're expecting something "revolutionary" or different, you're just going to continue to get how this expansion was designed and more iterations upon the content it included at launch. That's what Patches have always done.
The big, new features normally come with an expansion.
