KI could make money (I think) if zone pay were accessible through the web pages, i.e. by gifting someone particular zones or worlds.
Also, it would be much more convenient to have a way to pay for zones by the bundle instead of having to pay each time you try and enter an area. It's rather awkward to ask your entire team to exit a dungeon because you were trapped at the sigil by a pay to enter request.
Yes, sure, it's a great ploy to force you to become a member ... but seriously, KI, don't you think it would be much more pleasant and convenient if people could buy bundles that include all zones for a particular world?
