2 things.
1. The differences in armor appearance, well I thought it was kinda cool. Not sure why but I liked how the looks were different between factions. Since I normally play both sides of the same class scoundrel / operative, it was neat to me how different they looked. (other then cartel armor of course)
2. The Bug fixes, well I do not know of any game maker who does what you want and focus on bugs. I would suggest that you get every single person you know that plays plus about another 5000 or so to report the same bug because if its like a game company I used to work for the bug fixes are done based on priority, which was prioritized by the number of bug submissions. Unless if was a game breaking bug.
And the new content vs bug fixes - honestly that just business. Content pays the bills and fixing bugs does not.
I think if they just gave a bit more into bug fixes, appearance fixes (imo) they would help most current player base but then that would be my priority.
They should hire me! It is what I do, fixing bugs...put in a good work for me.
