Honestly in terms of how they made the expansions, they were ok imo. There were good and bad parts, but what I enjoyed most was that it felt fresh. Hear me out before y'all crucify me. Bear in mind I have not played Shadow of Revan, only the Inquisitor main story and for the KotFE and KotET I made a boosted to 60 Jedi Knight.
The Eternal Empire was kinda dumb yes, but it was interesting to see what could exist beyond the Sith/Jedi, while still being influenced by them. At the same time Vitiate jumping bodies kinda made 0 sense to me but I will take it (in terms of time span and what not, I know in the EU it was explained and possible). It was just a bit of a diversion from the constant Empire vs Republic. It was a fun diversion for me, not perfect by any stretch of the imagination, but enjoyable at the very least because of being different and new.
Arcann was fun and seeing what could happen to him based on my choices was interesting too.
Koth just plain sucked and was a uninteresting and confusing addition, even though I understand that there really was a need for a character from Zakuul to actually show the perspective of someone from there.
Lana was cool. The romance bug associated with her was not cool.
Also the architecture of Zakuul was really nice imo, they had some cool stuff going on there.
But the ending with the Eternal Alliance made no sense in the context of I am a Jedi Knight and I DO NOT want to rule an Empire. I wanted to destroy the throne in the end.
Still I am interested to see how they will resolve it in the future (if they do).
