Mix of both on and off-topic here, I think Same Sex Romances would be a lot more appreciated if they were exclusive, make SOME of both the original and new characters bisexual, where applicable and have straight ones, simply because it will make the genders much more important for classes, if you have ones that only gay and lesbian PCs can pursue, it makes everything that much more deeper.
I also think a great thing for companions would be to reintroduce killing them off, I mean imagine this(Massive Sith Warrior spoilers in case you are wondering what this):
My other dream is to have a Dark Side lesbian romance with Kira Carsen, where I can get her to kill off Scourge or Doc, etc..
Apply this^ level of importance with your companions and their interactions in every class and you'd be set for a far deeper and much more important experience.
