GW2 Gold players would start in their home map and work their way.
The home maps are available to fight in at all times. They are the only place you can find Orbs of Power that your team can capture to give your entire team bonus health. The Borderlands also give the home teams a starting point that is positioned to give them easier access to surrounding objectives so it's hopefully easier for them to capture the surrounding objectives and keep them out of enemy hands. The home teams also start the gw2 gold game with a couple of the objectives surrounding their starting point in their possession. We originally designed the flow of the maps to be such that GW2 Gold players would start in their home map and work their way in to the Eternal Battlegrounds or the home maps for other teams. One interesting thing we've seen is that since we allow access to all maps at all times, player behavior has actually tended to be the opposite of what we intended and people tend to start in the Eternal Battlegrounds and working their way back out to the Borderlands.
