I wish more people would get back to basics. The game was worlds of fun before Cataclysm and the need to fly everywhere. While it is an amazing freedom to have, that same freedom essentially chokes the life out of actual gameplay and exploration. For example. In TBC, in Hellfire Peninsula, In order to get to any of the Terrorfiends or the big boss in the corner (took 3+ people before heirlooms), you had to fight your way through Blistering rots:
Now, since Cata, flight has been reduced to 58 for Druids and 60 for all others. At this point you can drop in, kill fiends, and then drop right in on the overlord for the kill and fly away. No more challenge or cooperative game play:
The ability to solo most content in an MMO, and the lift off/touchdown of flying mounts has changed WoW from an MMO to an open world FPS. If people really wanted to regain that feeling, they would adventure with no money, bags, or heirlooms. Flying is just another service allowing you to get where you are going without caring where you are going or how you are getting there.
Most of us remember the LONG walk from Ironforge to Menethil Harbor without a flight path. Took almost 35 minutes even if you never came under attack (even though most of us did). Now, you fly out of Ironforge, flip a bitch, and come down the back side of the mountain. Takes 3 minutes... and you see nothing but snow, trees, and water. Gone are the days of passing other adventurers on the road and admiring their mount/gear. Seeing what they have accomplished and wanting to reach for the same. Now it's "What's the fastest way to get there and easiest way to solo this?".
Pitty.
