characters [suggestion]
I’m afraid the devs don’t have time to “loiter.” They do show up (well, ANet employees do, not all are devs). Look for the red ANet logo on their name as they run around in the game.
Then look at all the people swarming after them and the long strings of inane questions and comments that surround them in a cloud, and you’ll see why you can’t realistically set up a guaranteed talk-to-devs spot and expect it to remain respectful and spam free.
(I admit I tend to do a /cheer or a /salute when I see the red tag, but other than that I leave them alone unless I see them engaging in commentary, and then I limit my remarks to things germane to the immediate discussion).
I think he is talking of NPCs to represent the Devs, not the Devs themselves.
I think it could be fun to have that in game.
