I'm in Mooshu with my Death character, and everybody around me is level 38-40, while I currently just achieved 34. I think remember my life character was around level 38 in Mooshu too, so is my Death too low?
I don't really believe anyone can be too high or too low of a level for whatever they are doing, if you like a little of a challenge, stay at that level. If you want to be higher though, I suggest you do some side-quests.
I'm a level 43 (I think) Death player. I am level 43 (Once again, I think) because on most other maps I did the side quests. I saw someone as low as around level 31 (I think, I do not remember at this time. It does not sound right and that person probably only did the main quests.). All that stuff...
Sounds like a challenge! I can kind of relate tho - Me and a group of friends have all been questing together since day one (Give or take certain side quests and school specific things) And we are all now starting mooshu. We are: Myth - Lvl 40 Life - lvl 38 Ice - lvl 39 Death - lvl 33
Our Death friend has thought he was too under leveled for a lot of the game but he does amazingly well on his own. So never fret - Your just playing on a slightly more challenging tier! Good Luck!
