As I usually solo, I'm ok with the combat styles, gearing, UI, and other features. Yes, there are bugs but they aren't broken for my playstyle if you know the workarounds and they'll get fixed eventually.
What troubles me the most is the reduction in "production quality" in the content that is there.
I ran through Legacy of the Sith in a couple of hours on my main imperial. Killed Malgus no problems, no showstoppers after I figured out the workarounds.
What struck me is the lack of Star Wars story, cohesion, thematics, seemless story-telling, that I'm used to in this game.
I went online and heard that the republic story is much better than the imperial story in Legacy of the Sith. So, I logged in my main pub.
Just for old vs new content comparison, I ran some of the final Alliance FPs: Crisis on Umbara, Nathema Conspiracy, etc and they were every bit as great as I remember them. That was peak (or near peak) production quality.
The new content has seams, it has bumps, it lacks the same quality cut scenes, transitions, musical scoring, etc. Maybe the bugs that force people to call back to the fleet to progress at times are to blame for the rough ride but this week I've enjoyed playing the older content more than the new content.
If I could suggest anything from a long time player who still has a Darth Malgus statue in a box from launch, please scrub the production quality of this new content when you get some time.
Thank you.
