Um, it's been said multiple times before, Crica. Instant teleport and instanced-heavy content makes the game world appear empty and smaller than it actually is. If you could teleport everywhere instantly, you'd rarely see anyone out in the fields, they'd all be either in dungeons or main cities. Again, it makes our already small community seem that much smaller and may even serve as a deterrent to new players.
