My rogue is level 57 and her hearthstone is still set to Sunstrider Isle. I intend to not change it until 80. The only except is if I take so long that another expansion comes out. In that case, whatever is the new level cap.
I may be the only person who was glad to no longer get hearthed when ungrouped in an instance.
