And yeah, it always struck me as a bit odd that Sith Warriors, Agents and... (what's the third one, smugglers? O.o) had that imbalance where they actually had a choice of partners.
I count SWs as having 1 1/2 choices, actually. If you run your SW LS, then Vette is the logical choice. If you run your SW as DS, then DS Jaesa (psychohosebeast that she is) is the logical choice. Romancing BOTH at the same time could be bad for your health.
