Mooshu is a level 35 world if you are level 40 you have most likely spent a lot of time helping others. Kudos to you. If you are implying that Mooshu is too tough for a level 40 I think you are mistaken. I have run many characters of different schools through Mooshu successfully. I currently have both a balance character and a storm there and they both got there around level 35. you can tell what level a world is for by the level of stuff in the stores.
well your at a high level. even i have trouble with that its all right but if you have a lot of friends than they will have you help them alot. look im level 30 and im still starting marleybone. so perfessor Greyrose is right you start at your own pace. :D :D
It's ok. I finished Marleybone at level 30, and finished Mooshu around level 44. I didn't know the difference between side quests and story quests until my fellow friend from my school told me the difference.
First things first, relax. Everything is fine. As Professor Greyrose said, everyone progresses at different levels. Anyway, its better for you! The bosses won't be as hard for you and you will still lvl up pretty fast.
Everyone gets to places at different levels. For example i know this kid who got to dragonspyre at level 25 and beat mailistare. i don't know how because i am level 29 and am in marlybone. this kid said you need to be level 30 to get there. :D
