Well yes and no. You have those groups then the WPVP peeps, Rose Colored glasses folks, the people who want the game to be more tedious and time consuming (for whatever reason), the people that are thrilled to finally be getting new content, and the people that are of the mindset to give Blizz the benefit of the doubt and give this no flight thing a try. (think the last two will switch to the pro flight side when the newness is gone and realize no significant changes have been made to the game.)
Personally I don't see myself as a Blizz hater this is really the only thing I have ever complained about in game beyond 1 or two posts. I do see myself as a person that feels blizz has lost a great deal of integrity with this anti flight movement for a couple reasons.
1. Flying at max level wasn't a problem for 4 expacs and almost 8 years all of a sudden it is.
2. Bashioks comment " We want to slow down the consumption of content"
3. The fact they say they don't want travel to become tedious or time consuming but have yet to accomplish this or even say how they intend to accomplish this.
4. The fact that while they announced the removal of reforging and other things at Blizzcon on stage they avoided this subject all together. Unless you spend time on forums you have no clue this is coming. Hell according to my guildmates (talk to em on Skype) most still think that flying is returning in 6.1
5. The fact they are selling a FLYING mount at the Blizz store that is supposed to originate from WoD but yet won't be able to fly there w/no disclaimer given.
6. The fact they are selling a collectors edition FLYING mount w/the expac they don't intend to allow flying in (if they can get away with it w/out losing to many subs)
