All tiered instances should have reputation associated with them.

You could even offer tabards at exalted too (or even titles i.e. Chul, Hero of Mount Hyjal).

This allows Blizzard to place items they know will be in huge demand (like DST) as a reputation reward, and gives people incentive to keep coming back to an instance.
