I agree that 3 would be the most ideal so it can be a tool for people who want and need it and everyone else can carry on the way that has been working for them. Of course suite mates are no promise for CR but it's at least something new to talk about and a possible stepping stone to CR.

Personally, as someone who has probably lost about 90% of her character's CR and am kind of feeling down on the game overall, it would be helpful for not only a chance to make new CR but just to distract from Clara's miserable IC state.
