I just decided to give SWTOR another round and figured I would start with the HK-51 stuff. But I had some questions. There are a ton of guides out there, but I found very little concerning the following questions. Any help would be appreciated.
-Once HK-51 is unlocked, is he available to all Legacy characters or will he have to be assembled mutliple times?
-Does he have unique in game dialogue that would make it worthwhile to use him while leveling a new character?
-Does he have dialogue tied to Affection levels? If so, what are his preferred gifts? (I assume trophies and weapons from a lore standpoint)
