So you think it's fine for Prot warriors to choose a weapon that makes them take more damage and removes some key abilities.
You think just because people will try to find the easiest solution to a problem the devs should give everyone the easiest possible option, far outstripping class abilities for those issues.
You think high-end raiders will be happy getting the same rewards as LFR players, indeed they'll be happy if all raids but LFR are removed and they can choose ways to gimp themselves.
Just these facts alone show that you don't really understand much about WoW, game design in general or the tricky balancing act Blizz have to go through to make sure when they please one group they're not undermining the sense of accomplishment of another.
Literally the fourth time I've pasted this answer, you can even click the little blue icons to see the other posts...You still havn't answered my question, all you've done is ask questions...
Forgetting the psychology bit as that seems to have thrown you for a loop so you forgot to answer the main part of the question, does that mean you would or wouldn't be happy if there was a "fly mode" that halved quest rewards and doubled the requirements for Covenant dailies?
Or there's choice 3 - the devs balance the game in a way that trying to find the optimal way is the most fun. Which is what restricting flight has done.Now I'll try my best to explain the issue with your thinking. You've narrowed the choice down to 2 things. (there's more choices but these 2 are the ones you've basically pointed out so I'll focus on these.) The choices are playing less optimally but more fun or playing more optimally and less fun.
