I’m going to second what other folks have said already. Uninstanced Salma was a great spot for many roleplayers on Tarnished Coast at least. No one was bugging things or crashing the server so I have no idea why there were more invisible walls put in.
All this does is drive more rpers from this game and let me tell you, rpers are a group you want. We buy stuff. A lot. We support you and stick around long after the die-hard PVE fans and PvPers are gone.
You have to give us something to work with A-net, and not keep taking things away.
