So, getting multiple characters through 'Onslaught' has been a pain and now 'The Legacy of the Sith' is meant to continue the story. However the first thing on my mind about what is to come is
Concerning the Story overall what with the whole saboteur arks for selected characters, I'm probably over-analyzing it but I can't help but think that either 2-5 years from now Bio-ware will continue to build the story to a nexus point to where we can actually take our faction locked characters and literally switch to the other faction(Dark Jedi becoming a Sith, Imperial agent converting to SIS agent). I can't help but feel that this is Ultimately where the SWTOR Story is headed and I'm not feeling hopeful, the story is progressing but I get the feeling that at some stage those that are playing the saboteur will eventually get found out.
When the game first released it was about the story overall, the ability to interact with story characters, companions and flashpoints alike, then it was a combination of story and interaction but these days the only story that gets any attention is the Main Story and the flashpoints are just pure combat without interactions, if this keeps up the whole idea and purpose of Dark side or Light side will become redundant despite being a Core Function and focus in the game. In my opinion there needs to be more content that focuses on Companion side stories as well as proper companion to companion interactions(Vette+Risha, Ashara+Jaesa, Khem Val vs Ak'ghal Usar) as well as additional recruitment missions for the other inaccessible companions.
