I think you might have hit the nail on the head there...
That's something I haven't thought of and makes alot of sence... the only reason I'd think it wasn't would be that Nurse was a Resser so it might be time to move to something else... Guild Guard, Stitched Together, Preformer/mannequin or Gremlins.
That's an interesting one... and for those only with 1 or 2 factions then it might get them to go for more... I'm still hedging my bets on Molly though.
It all depends on what the Drawbacks to them can be... Lets say that Lady J gets a boost to attack but there might be a reduction in defence... or not able to use Soul Stones when in Avatar form...
It's really going to be a wait and see I think
