Found this one today hope you like -
Get yourself a Group for boarding party hard-mode preferably people that want lots of these tokens
Halfway through the instance you will find a mini-boss called Major Alvena and her 2 droids. CC both droids kill Alvena, loot and then die.
When you come back in Loot the boss and repeat as she will have respawned due to you wiping!
hope you enjoy.
