There are very few good babyface GM characters because babyface GM's are basically "good" people who don't lord his/her authority over the wrestlers on the roster and the only ones who have issues with them are the heels who complain about how they're against them or don't treat them with the respect they deserve, etc.
When Foley was announced as Raw GM, it should've been obvious that the day was coming in which tensions reached a fever pitch. Foley is a nice guy while Stephanie's character is that of a malicious, cold hearted bitch who likes to use her position of authority to screw with the lives of babyface wrestlers because she gets off on the power. Such two polar opposite characters are going to clash and in this case, you have a formula that's difficult to alter. Even though Stephanie is close to 40, her character still comes off like the Billion Dollar Princess of the Attitude Era a lot of the time, her character is this elitist snob who's management style is tyrannical and sees anything other than cold, calculating and manipulative to be a sign of weakness that she'll exploit.
Stephanie's heel character is a great one, but she's gotten too much exposure the past several years. You also have to take into account the general lack of interest in on air authority figures because it's been a constant presence in pro wrestling since even before the Attitude Era but with much more emphasis placed on it. Now what this likely means is that there'll be another GM appointed who'll be more along the lines of Stephanie or he'll/she'll be a spineless jellyfish that can be easily bullied or manipulated.
In Foley's case, however, you had a payoff that might damn well be worth it. People like Foley, he's a sweet, laid back, easy going guy that's easy to like. He's also someone who's given his health and risked his life at times to entertain wrestling fans, something that fans will not forget nor should they. What they saw on Raw Monday nice was two lousy rich assholes without any connection or care to ordinary people beating up what amounted to a defenseless 51.5 year old guy who can't really defend himself anymore because his body's simply too beaten up due to 3 decades of leaving it all out there in the ring. When Seth Rollins' music hit, Rollins probably got the biggest pop of his career, if you don't count his MITB cash in at WrestleMania XXXI, as he came down to stand up for Mick Foley. This may well have been the thing that gets Rollins over the hump to being a full blown babyface that fans accept as a babyface despite his time with the Authority.
