I'm not to keen on needing two characters from opposite factions to get HK-51. I play alternate factions on different servers. It already feels like I'm being punished legacywise for splitting my characters, but I felt it was worth it in order to gain the use of more character slots. Forcing me to create a character and play them up (twice actually, once for each faction) just to gain the new companion seems more annoying then anything else.
