Did the migration to RPPM make Colossus suddenly a whole lot better than it had been? AskMrRobot has begun recommending that I swap out River's Song for Colossus and I was kind of shocked by that.
To Clarify: I'm not looking for AMR hand-holding or explanation, just didn't know if there was some under-advertised change to Colossus that I'd missed. The discussion above leads me to think that the RPPM change is at best a wash, possibly slightly negative.
