I hope this never happens. You're supposed to have certain awards because you've achieved something, and your tangible award, be it a title, minion or mount, are proof of that. You shouldn't be able to obtain that unless you actually ran the relevant content. Then we have things like the tank mount achievements that were put in place with the specific purpose of encouraging people to play tanks more (and I'm one of the proofs it's working cuz I want that damned armored bear and I never thought I'd ever be tanking this much). They have no reason to give you alternate ways of getting those awards when some of those achievements were put there to force you to play the game a certain way to begin with.
