it will effect it and it wont,

insta travel takes away from the experience that you are Mr./Mrs. Adventurer not just a character on a game by not allowing you to feel like your traveling at the speed you should be and experiencing all the sights and sounds you would be.

it doesn't effect it as well. if you never experience the joy of the airship ride or boat ride then you wont always feel like your missing out on the content.
