Let me just clarify a point here: Bureaucrats are identical to admins except they can make other users admins, or take their admin rights away. That's it! Bureaucrats can do everything an admin can do, such as deleting pages, protecting pages, blocking users, and access fully protected pages, and an admin can do everything a bureaucrat can do, except for giving other users admin powers. A bureaucrat cannot rename users; only staff can do that.

Also, the only thing a rollbacker can do that normal users can't is undo all edits by a person on a single page really quickly. Not very useful unless there is large amounts of vandalism.

Hope this clears some things up.
