I disagree, as I mentioned, I very much want to play with other people, In fact, I normally ONLY play if I can play with other people, my wife, my son, guildmates, and a few friends. Yes, I met some of those people through the game, but I didnt meet them running around the world trying to get my quests done. I met them in dungeons, and raids, I met them doing GROUP content. not in single player travel=immersion time sync content. I met them through friends while looking for more people to do group content with.
I always laugh at the people who claim that those of us who like flying just want to avoid people and MMO's arent for us. Most of us want to play with people, most of us want persistent worlds that evolve, change and grow. Most of us just dont enjoy the mini content that is moving from one place to another.
Now I wont disagree that bad game design might be the reason we are in the situation we are in, but flying didnt cause the game to go in the direction it did. As far as bad design being the reason people want to avoid the world, maybe its because there are aspects outside the world some of us do enjoy? Dungeons, raids etc? I just dont see travel adding anything useful to the game really. I understand I am in the minority, but its pretty much how I feel, I would rather spend the time in my MMO with the multiplayer aspect of it. Now, add more open world group content besides wham bam thank you ma'am world bosses, and well, I would spend more time in the world, and enjoy it.
