I came across an interesting mechanic while hunting for WRE. For the [Curse of Arugal] there was this chair in Pyrewood Village that "only one person could sit in at a time".
This got me thinking about all those unfilled Tavern and Inn chairs in the world. What if we made them [XP Chairs]? Chairs that passively give you XP when sitting in them! (Obviously, you can't be AFK for this XP gain.)

Battlegrounds, Dungeons and Daily Quests are all tools to create an MMORPG experience. To motivate people to log on and be part of an online community.
I say, BS-ing with your friends online should definitely be a part of that. So let's reward it with XP.
