People don't do it because instead of getting a mount, title, tabard, pre-raid gear, you get garbage. No one had a problem with doing dailies in Quel'Danas, Molten Front, Isle of Thunder, and even Timeless Isle. Did anyone even say anything ever about no flying in those areas? Maybe a little before the patches were released, but they didn't keep making them no-fly zones because people hated it.
The quality of the quests are not the problem, you're digging pretty deep if you have to put words in my mouth. I never said the actual questing was bad, but doing things for the sake of doing them is not how you make MMORPGs.
Do the apexis daily past your 5000 requirement for the legendary...then what? Get the gear? The gear that's worse than LFR gear? What?
