The only gold sink I found to be too expensive during the BWE was the respec one. It was actually prohibitive, which really pissed me off. As far as waypoints go, I think they should make traveling to any major city completely free, and calculate cost of travel to other waypoints both by distance from your current location, and distance from the nearest major city. What I mean by that is that traveling to the waypoint closest to my current location should cost about as much as traveling to a waypoint close to a major city, even if said city is on the other side of the world.
The reason for that is to avoid the silliness of people going into pvp-lobby->LA->Major city just to save the fast travel cost. This will simply allow people to bypass having to needlessly load 2 extra areas just to travel to a major city at no costs.
