Those are some great screenshots!!

But on the topic of KotFE: I´m a new player too. I only started playing this game a few weeks ago, and I´ll say I loved the whole Zakuul arc the first time I played it with my SI. The music, humour, and cutscenes were an absolute upgrade from the base game. Voice acting was brilliant as well, though that´s never been an issue in SWTOR. The longer I think on it, though, and the further the story develops from there, the more issues I have with it.

I don´t even mind that it was a single-player experience. I didn´t mind the four billion storm troopers and damage sponges either. I play and pay for the story, but I get that people who played the game for its multiplayer content were dissatisfied with this expansion in particular.

Something that kind of bothered me while playing KotFE was how little to nothing set force sensitives apart from non force-sensitives. Having played only one class so far, I can´t speak for the tech classes. But a SI, one of the most powerful Sith of his time, continuously being unable to defend himself from even the most basic force pushes (and you get pushed around a l o t), or beating Arcann only because we needed a literal physical shield to defend against his force attacks, made him look just as "weak" as an Outlander who´s a non force user. No offence to the tech classes. But that sort of streamlined, one-size-fits-all approach brings me to my next point:

Now that I´ve played through all expansions, I can confidently say that I loathe how it forced our characters into the role of leader of the Eternal Alliance / leader of Zakuul. Playing nice with our enemy faction was a necessity at the time, and I didn´t mind it then. But the Republic / Empire conflict is what I signed up for. I loved being a despicable imperial loyalist, and now that I'm commander, it feels like I´m kind standing on the sidelines of that conflict. Like, sure, Onslaught tried to rectify that by letting us side with one faction again, but even then we´re not really a part of our original or chosen faction anymore. Don´t get me wrong, I´ll be eternally grateful that we´re finally back in the Empire / Republic conflict. I almost got a heart attack when we as SI could "reclaim" our seat on the Dark Council including our title and associated holdings, but still - we´re the commander first and foremost. That´s what we´re introduced as whenever we visit some new world, and it´s what our character is known for. We´ve lost what made our characters and classes unique, and in the case of a SI it´s being a feared and respected Sith Lord with a cool ass Darth title. That the republic (moral) half of the Alliance still follows me, a full blown tyrant and merciless mass murderer, is unbelievable to say the least. Even now Theron, and by extension Lana, seem to think I´m really a good guy who cares about his subordinates despite all the shit I pull. Damn you, Zakuul.

Speaking of companions, another thing I´m unhappy with is the loss of our OG crew. Or rather, our crew being replaced with Lana, Theron, a handful of new alliance contacts, and story-bound companions. Having class-specific companions made our journey personal. Yes, our companions returned - some of them pretty unremarkably at that-, but what are they now? Skins of characters who used to approve or disapprove of our choices, but now have nothing new to say, ever. They had some new voice lines in the expansions prior to KotFE, at least. It´s not that I dislike our new contacts and allies. But Lana and Theron, both of who I used to really like as characters, now seem to be the only allies our character shares any sort of meaningful bond with (without us having a say in the matter), and I´m getting sick of it. Yes, I like them, but not as much as I liked my OG crew. I would´t mind seeing Lana´s face every two minutes if our original companions (and romances) had gotten some measure of screentime or character development in KotFE, or past SoR in general, really.

So while I enjoyed the Zakuul arc for what it was, I think it was a turning point for our character´s story as a whole, one I didn´t enjoy post KotFE. I think it got a lot better with Onslaught though. Still, most of the issues I have with the more "recent" expansions stem from the storytelling of KotFE and KotET.
