I find it interesting that quest NPCs will actually be in the flashpoint as enemies instead of just random sith/jedi models.
The character models have always been there since the game was first released and since both flashpoints apparently aim to reuse most of the existing assets in both planets, it does make sense that they'd use those very same Sith you get quests from.
I assume the same will happen on Tython for the most part. Wonder if a slight detour to Kalikori village is possible... Unfinished business and stuff.
