I agree. I would have rather waited until KOTFE could include the stories of older companions, vs. just releasing it with new companions. I mean, there is plenty of content to enjoy on SWTOR including Hutt and Revan stories. Plus legacies etc.
We aren't League players or Warcraft players, we don't care for JUST new stuff, we like stories, and that means connections to our past (companions) -- more than just some dialogue.
Until then, for those who have already started KOTFE. Just pretend that always, in the back of your mind and in your heart, you are fighting FOR your old friends, ALONGSIDE new ones.
