I usually play the Empire. From the moment that the Emperor stays always in the Throne of Power (recruiting, training Jedi -SWRE change-, and giving that military bonus to imperial caracters) I send each captured Rebel -accompanied- to Coruscant. The Rebels that try to rescue their comrades are falling victims of their lack of preparedeness to deal with 18 troops, 12 noghri, 12 impcommandos and all the Dark Jedi and they end up "languishing in chains in the depths of the Imperial Palace" -or Ysanne Isard's Lusankya SSD But still, why abduct and jail them? It's easier to kill them. That happens too if you try to abduct an injured Rebel with high Combat Rating like Chewbacca. On the other hand the diplomats like Borsk Felya come willingly to you even with 3 Noghri (2+1 decoy).
