I’m team Lana, myself. Having had a major role in nearly every expansion since launch, she’s had more time to develop as a character and romance than pretty much any other companion. The progression feels more natural being spaced out over multiple stories, as opposed to being crammed into a couple of hours of gameplay.
All of them. I did play throughs on all 8 characters/classes. Republic and Sith sides both. I played SWTOR to death, daily for years because I had no money and was in hard times. Haven’t touched in in 5 years now though. I want to come back but so much has changed I think I would be lost.
