Guild Wars 2

Hey there GW2-ers!
I have a small suggestion for the guys at Arenanet.
Here it goes. When you drink a Mistery Tonic. Some may turn you into a bird. Why can’t the bird fly freely over mountains, between trees, through villages… Why isn’t this possible? I would like to do that.

What do you guys think?

Also, what about Water Mistery Tonic? A tonic that would turn you in a fish so you can easily swim. What about THAT?

Flying over mountains would break the maps and jumping puzzles

Are you saying that you have difficulty swimming in your usual form..?
