IMO, the one thing WWE is missing (besides the fact that we're all tired of this basic plotline) is that Austin won vs. McMahon just as often as McMahon had a win, if not more. With the Authority, the odds are getting SO stacked against the good guys that any victories they win are transitory at best (and Daniel Bryan needing to be stripped of the title REALLY did not help in that regard, particularly with the logic hole it created later of the 30 day rule not applying to Brock). If it gets much worse, the Authority could disqualify faces from matches for being too sweaty, or for having the letter E in their name. You make the situation TOO hopeless for our heroes and we stop caring. And if one or more of the three "fired" turns heel on Cena over it, you just made them look like idiots. In Dolph's case, you just shortcircuited his career (then again, Cesaro was ready to GO as a face after Wrestlemania, and they screwed that up.)
I agree that people need more promo time to give us a reason to care about them (and maybe even bring back managers into widespread use if they can't cut their own promos). Ryback's promo last week was excellent, even though he's not known as a promo guy. In retrospect, it was only to set up how heartbreaking it is now that he's fired.
Ambrose and Wyatt has been an excellent feud, though I hope it's over now since one of those two is going to get seriously hurt if they keep going at it. If I were the writers, I'd make them into a tweener tag team/mini-faction. Have them go maul both the Authority and the faces alike.
