I hate to be the meanie here, But it will always be a lag fest
I don't think they plan it that way it's just that people tend to congregate where storage is. The only way around that is to set up proximities around the storage keepers and make it so people can only shroom in a certain place/places. Then they would be so spread out it would result in whole new group of complaints. That they have moved the storage keeper away from the spawn zone is a good thing though.
I agree with the quest bugs, I can't even give up Henneth alliance, it just sits there. I mean for real, quests are a huge part of us being able to level. They should really be a high priority.
