I think ya'll missed my point, or didn't fully read my post, or something, because I said quite explicitly that I am fine with zones being instanced. That's not what I'm talking about. The area you can see above me is not some out of bounds region; it's in the middle of the zone and there are mobs up there. I can go up there and run around, but in order to get up there, I am forced to go down and around a very narrow path that circles about a mountainous area that should just be climbable because it's in the middle of the freaking zone, please stop blocking these things off with invisible walls.

There's no exploration within zones in this game, and it's very frustrating. Everything is canyons and invisible walls.
