I'm not clear on what this would entail for me as a Mobius player, but I'm guessing the following.
1 - I'd need to leave the Winters powerplay faction.
2 - We're in Empire space, so we're going to be Empire aligned (ugh

) and that's going to be a problem for me still working on my Federal standing. I really would like the Corvette when it is released.
3 - Is joining the Mobius in game group automatic? If so, will my federal alignment be problematic for the group?
Basically right now, whilst I'm happy playing in the PvE group, joining the Mobius faction in game would not be right for me.
