My personal overall opinion of RotHC is pretty straight forward , its release was a much needed reset button. The story could have felt more personal (no companion interaction or conversations?), the progression could have been tuned to be a little slower, the gear shift could have been less jarring , and there could have been a bit more "Muchness".
RotHC might as well have been called a Customer Appeasement Package, which despite my negative sounding demeanor is something the game sorely needed. SWTOR needed to get a clean slate that didn't involve NGE caliber sweeping changes. I just hope they have a real expansion in the works that involves much more Muchness.
