BW should really give us an ETA. Rumors(or is it facts?) say that it may not be available to companions that you have already progressed on, and if so, I want to know if I should progress on them or not.
Furthermore, I don't think its fair at all to only make new companions with SGR options. That would give us who wants it, much less freedom of choice. I know, I know, in real life no one can just pick a partner by pointing at them, but games are made to delight and entertain, not to hinder or bother, right? The best option imo would be to make all companions and npc's available for SGR
I would appreciate if BW worked on this ASAP. Just like how some things irritate some people, the lack of SGR in the game is currently making me unable to really enjoy the game, with all the vague information about the implementation.
