Guild Wars 2

I have found that the green star indicating direction to the next location for my story line often has tried to route me through Asura Gates that are not yet available. This has happened at least 3 times to me where it has sent me running across a region just to find that I cannot get there from here. It would be really nice if whatever algorithm that calculates these things could also account for whether the asura gates are actually usable by the player.
