That the trading post is nigh perpetually “down for maintenance” is annoying but ignorable. I’m sick of trade spam in every zone, but I’m sick of guild recruitment spam in every zone, too.
What is really bothering our guild is that the grouping interface is not working properly. I think players can get to the same overflow/layer of the world/whatever. It can be hard to tell because, unless you are within sight distance of each other, the avatars are blanked out and you get a “join” button they way you would if you were not in the same instance of the world. Speaking of instances, joining each other there can be spotty. We have had people unable to join each other in personal stories and in dungeons.
Some of the pain is ameliorated by the game’s mechanics that make formal grouping less necessary, and this is less bad than Asheron’s Call 2′s lack of functional chat around launch, but one of the basic things you should be able to demand from a multi-player game is being able to form groups with your friends. Well, we can form groups, but they don’t work right, which is just inviting us to try it and hate the experience.
Finding family members at grocery stores and real theme parks would be so much easier with dots on a mini-map.
