Guild Wars 2

It feels like guilds would benefit from like an instanced guild hall where guildies can be teleported to a guild hall where they could hang out duel within a battle square, and just talk! Seems like a simple idea that would greatly help guilds and their communities!

And the chance for it to get upgraded with merchants npcs, bank, asura portals, maybe even some mining nodes and stuff : p

There have been countless guild hall request posts. I suggest reading some of those.
