Atm the moment I´m stuck on my 2nd Visit on Zeffo after Kashyyk.
I absolutely find no way to reach the mission target or even back to the Mantis.
Every attempt leads to locked doors and after loosing hours to find a way, you return with no health/stims left exactly to the point where you lost track before.
So yes, fast travel to Mantis or multiple save points, that you can choose from, are urgently needed.
And btw, please make respawning of enemies optional on story mode.
For an experienced everyday gamer this may be a nice and challenging experience.
But if you just want to relax and enjoy a little Star Wars feeling in story mode, this game offers far too many frustrating moments.
