I can only assume that would be RS Blackwell, who is now 'doomed' to have a Def rating no higher than 13.  Seems like 'fancy-ketchup-quality' on a team with very high standards.  Best to just let him go by the wayside, Steve, and not waste any more CP on him this or next season.  No doubt he'll be replaced by a 5* soon, as Columbia do really, really love their top-quality RS players...

I do weem to do well at RS but Blackwell is at least the 3rd one I've messed up CPing. That's why I started keeping notes on what slots I had left  to make sure I didn't accidentally leave anyone until too late. This was simply a misclick.
