I just re-subbed and I feel very lucky so far but frustrated with some of the design choices in KotFE. My Sith Sorcerer got his farewell letter from Ashara, but I'm still pissed she's missing from KotFE. My vanilla level 40 Jedi Consular was able to initiate romance just fine but I toyed with them and then declined to pursue it, she remains unattached and full dark side.
That being said I have not taken a second character into KotFE yet as I'm a little upset about the missing companions. I am reluctant to take my Trooper (my first character) into the expansion as Elara Dorne has been by his side for too long and he is straight laced and Light Side all the way, loosing her would be traumatic to his psyche and it would just be sad to play him without her. My Smuggler however is a dog and has no problem leaving his significant other behind, he's been cheating on her behind her back with every woman he can so he will be the next one to enter KotFE, however loosing Bowdaar will be hard.
I haven't really looked at my other high level characters and will likely focus on hitting 50 with the 2 classes I haven't done that with yet (Jedi Consular and Imp Agent) anyway. So other than the Smuggler, I may wait until the next chapter to take any more into KotFE.
