Be it this or that - this thread isn't exactly going anywhere, been stuck in this loop for ages now. Some like current situation, some can deal with it and some can't, no matter how many times you try to tell other side how you "love" situation X, it's not going to change things. And even if "anti-flight" or "pro-flight" people somehow would convince some players to "join their side", would it even change anything in the end?
We've all seen that Blizzard doesn't utilize or even attempt to change flight or content to be fitting for each other, they just slap it to world and let it be. In it's current form, flight is an issue to me but if they'd do some changes, my view might change. Can't just design world for ground usage and then add free flight to it. So Blizzard is going with the easy way, simply delaying it as long as possible until that content has been drained enough to be too "exhausting" to be done on ground and try to extend subscriptions with free flight, easing the load by cutting travel times, reducing mobs between points (they are usually on ground), and so on.
I had enough with their design decisions, I wrote feedback and froze my subscription. Had they fixed the problem(s) earlier, they could have still managed to get my subscription back, but since it took them whole expansion to do it, I'm already lost to another MMORPG.
