If it's not fun, simply stop playing. It's that easy. The rep grind for flying is laughably easy as it stands. I would honestly prefer it if flying was much much harder to get, or not in the game at all. It fucking ruins world pvp.
This is the major problem with retail. I want shit to take a long time, it's an RPG. Wow is at its best when everything is at a snail's pace, giving you time to make small, incremental upgrades to your character and to really explore the game and the people you play it with. I keep seeing these threads about retail that basically boil down to "GIMME IT. I don't want to have to do anything, just gimme!" And that's gross.
Classic is where its at right now.

Flying is way less fun than you think it is honestly. It involves mounting, flying upwards, pointing yourself towards an objective, then going afk. I think that flying is cool SOMETIMES, but overall it kind of ruins world pvp...unless i can get a net shot on your ass.
I'm enjoying classic more atm, you can run but you can't fly, and I will catch you eventually
