The fee for traveling to waypoints in Guild Wars 2 has been justified as a gold sink. I’ve seen no other justification, and I don’t think it’s intended to discourage using the fast travel system.
I don’t understand this. Yes, gold sinks are necessary to prevent inflation. But the amount of gold being put into the game is also a variable under the developer’s control. In cases like this, why not reduce the amount of gold dropped in the first place, instead of adding an annoying sink to remove it later?
It seems to me that the amount of gold flowing into the game should be matched by the amount flowing out through interesting gold sinks, and if there aren’t enough of those the amount flowing in should be reduced. But economies are complex — is there something I’m missing?
