I think leveling after cata is perfect! All quests have a really good story behind, but they have no more challenge in it. It's not good, it's not bad. It's just a different game now with different gameplay
Does timeline (https://elysium-project.org/timeline) have all patch changes? Or it's just the most importants? What about fish schools and floating derbris? I can't see any of it. Will they be added in future patches?
