We already have enough fools on mounts blocking NPCs and other things. Don't exacerbate the behavior by being more obnoxious. Moving the AFK kick-out spot for Island Sanctuary was one of the best things they have done for the game. Now, if they could just learn to have collision detection around NPCs and things we interact with so we don't have to keep holding down X to be able to click on something without 50 people standing right on top of it, that would be even better.
