Just my two cents, but I would like to see the Party Jawa return. Having started at launch, I was on a SWTOR hiatus when it was offered and have been wanting one ever since. Over the years, BW has been throwing numerous items back into the game that were once thought to be exclusive, for example:
First, Second, Third year Cartel packs
The 'Containment Officer' title and armor that dropped at the first Rakghoul outbreak on Tatooine you can now purchase through the Rakghoul vendor on fleet (albeit expensively)
Life Day decorations, vehicles, etc. that people once paid for with CC's at prior events were available at the 2015 event for Snow Covered Parcels
The point being, there is little to no exclusivity in this game, so why not bring it back...
