You have to remember the basic reality of storytelling is that villains are flat-out more interesting than heroes.
Who's the more interesting character: Superman or Lex Luthor? Batman (the ost interesting hero in existence) or Joker? Luke Skywalker or Darth Vader? Harry Potter or Voldemort? Edward or anybody out to kill Bella in the Twilight books?
Add to that the reality, in the world of pro wrestling, that the big, muscular guys always end up being the heroes (Hogan (in his prime), Cena, Rocky, now Ryback - same list from earlier, but I digress). Meanwhile, the leaner, meaner, smarter guys end up being the villains (Punk, Edge, Michaels in his early work, HHH before he bulked up) and most of us think that Daniel Bryan is more in that latter category than the former, which suggests that he'll end up spending most of his career as a heel. Somebody's gotta be around to take on the Rybacks, Cenas, Rollinses, Sheamuses, etc., of the WWE. Since the future boss is so high on DBD, that does bode well for his future and for his future success. He'll end up having multiple world title reigns, if for no other reason than the fact that most people find it more interesting to watch the hero chase the title than hold it and beat everybody in defending it, which most fans tend to find very boring (as we did during that 380-day WWE Title Reign by Cena about 6 years ago).
So, relax. DBD will be around for a long time and will always have something to do.
