it's because having a different opinion then you can't be possible right?
I think Legion has worked out very well so far enjoy'd world questing allot. the whistle was a good compromise.
Personally im not a fan of flight in MMO's. the only MMO i think it was done right was Aion, but that was only 'gliding' which worked well for that game. Legion for me proved that's i think this game works better without flight for the community as a whole. People always say that it was the pink glasses effect (classic game). Well ... nope.
that said, i don't mind them adding flight now for those that miss it. live and let live
