you only get 4g for completing a level 70 daily now but you get XP for it.
probably not as much XP as an northend quest but it's not bad, say 12k instead of 20k @ level 73.
the best part about the daily is that you already know how to do it and there is NOBODY out there, you have the whole place to yourself, I finished the dailies in record time skipping collection quests of course.
imagine flying out to the boat and never having to leave the flight path to complete that quest.
