You mean like introduce new classes similar to how Star Trek Online just introduced the Dominion player faction? (start at a high level)
If they were to introduce new classes I would go with Imperial Trooper or Republic SIS Agent.
Probably this. I would have thought they wouldn't repeat the same mistakes they've made in the past but I'm not sure anymore. I wouldn't be surprised if they're trying to make this game unpalatable so players go to Anthem.
Don't forget about the second clone. I don't think it was named but Vader had successfully cloned a dark side version of Starkiller that obeyed him and ether didn't have or didn't care for the thoughts of the other clone. (He appears in the dark side ending of Force Unleashed II.)
Not sure how he can come back after we impaled him on that space station which then exploded into tiny pieces. Maybe if Acina is good at jigsaws she may have found a way to clone him? Though if she can do that, I'm not sure why she would pick Malgus.
Then despite my personal opinion on Vowrawn my answer is no. My vote is for Acina.
The time of the surrender was one year after the player went missing? According to Lana in one of the early kotfe chapters. She also says something about the only member of the dark council to remain active was Acina. So for now I'm going to assume Vowrawn's surrender to the Eternal Empire lost him a lot of respect in the Empire.
Maybe the Sith were able to retrieve her body and resuscitate her? She's in charge of the Sphere of Technology? Maybe she's got some clones on stand by? Maybe some kind of cybernetic enhancements?
I was thinking more along the lines of it being motivation for players to try out the harder levels. It might take some time but I would welcome the challenge.
Wasn't it the Minister of Logistics who surrendered to Zakuul on behalf of the Empire? Assuming that's not a reference to Vowrawn, it sounds like someone who works in the same profession as him. Acina was only a Darth at the time of the Zakuul Invasion.
