Then i have to understand that you never use your hearthstone, your mounts or any kind of transportation or instant teleport like a mage portal. I'm not going to be as agressive as Lincoln Lawyer, but that's a really bad reasoning, and i'm sure you use all those things in a very natural way.
First, that kind of immersion is up to you, you don't have to spoil it, no one will force you to use any kind of transport if you really want to walk all the way while singing about Tom Bombadil, you can do it. Actually RP and immersion is something that is up to the player.
Second, the point of transport is go from A to B. That's because there is something in B that you want to do. In most situations, that thing is playing the game, getting immersed in the game. Today i went to Timeless Island after a veeeery long time, how did i get there? i used the flight path from the shrine and alt+tab while my character was unable to perform any other action (actually, i posted a reply in this thread meanwhile
) then when i was there i spent one hour killing stuff and having "
fun". I am sure that this same scenario repeats constantly for a lot of players, althoug we don't have any problem at all enjoying the journey the first time.
