I like exploring things in games, but in MMO's it's never felt rewarding or fun. Walking alone through an empty area, largely void of players, just whacking at mobs that happen to be there just to get from point A to point B always felt dull, boring and time I could spend having fun. For people who like to do that, they still can (just don't use teleports), but I don't always have a ton of time to spend online and on those days I'd rather use the little time I have doing something fun in the game, not meandering along trail to get to the fun.

Exploration was a large part of Guild Wars 2, but after a while it came to feel like a boring, monotonous chore. There were open world dungeons, but people rarely did them. There are tons of events, but there's rarely anyone else wandering around in the same area to do them with. Everyone would end up funneled farming, doing dungeons or other instanced content, off in PvP, or chatting and RPing in the major cities (and sometimes in the world). I couldn't imagine doing everything I did in that game without Waypoints (teleportation) available after discovering them... it'd make getting to large events a pain, it'd take an annoying amount of time to go from one section of the world to the other if your guild had something planned in the Shiverpeaks and you, unfortunately, logged out for the night after a run of Arah and then have to fight through six or seven zones to get there.

I find exploration and lack of teleporting more fun in single player games, where you come across events, ruins, temples full of fun, interesting ways to develop your character or that contain interesting armor that holds a lot of lore to it, or something more like that. Going on adventures while traveling.

Sitting on a boat for five minutes basically afk is neither an adventure nor is it fun.
