This is by far the worst idea I've ever heard of, seen or had the displeasure of reading. Who in their right mind would suggest this, or let alone think Blizzard would actually implement it?
If you don't like flying, then don't fly. No one is forcing you to, and the entire game is still accessible while walking or on a ground mount.
This is like the pvp on pvp realms not being fair. If you don't want the chance, then don't roll pvp. If you don't want to fly, then don't fly. Simple as that.
