It is refreshing to see someone posting something positive here.
Yes 7.0 has some pretty serious issues, the UI is painful, it has a bug list as long as war and peace and the actual story release is very very short.
However, as someone who plays for the story I am NOT completely disappointed.
I have now played through all of the new story content on both imp and pub loyalists and imp and pub saboteurs.
The Manaan section did fall a bit flat for me and I thought it felt like a filler to allow players to get used to the new layouts and combat styles. The Elom flashpoint did move the story along a bit, there was some character immersion for both sides and some movement in the saboteur story for both sides.
I like the fact that my Jedi sentinel can now use force lightning, it fits her story that she would experiment with dark side abilities since she is in a relationship with a sith.
All of my other chars now have a stealth ability if they did not previously have one. This is hugely helpful.
As far as the story goes, BW did say that the story would be released gradually over the next year. It would have been nice to see a little more in the "expansion" which frankly feels like more of a content patch. But this basically strikes me as a prologue to the next phase of the story. We have been promised more so personally I am content for now to give BW a chance and see what they produce.
I just hope we're not waiting months for 7.1 or it could drag a little with the volume they have given us so far.
