Diablo 4's map appears vast, covering a multitude of hubs as well as biomes and dungeons. At first, the player is required to walk around however, they'll soon get the ability to move between various waypoints, gaining access to more and more as they explore new regions.
Teleporting allows the return trip to Westmarch to take out unnecessary items, upgrade gear and interact with other players a far more pleasant experience than it might otherwise be. It also allows travel to be much less difficult. If the player doesn't have a compelling reason to do otherwise, it is almost always preferential to use teleporting instead of walking https://www.mmoexp.com/Diablo-4/Gold.html.
