It's not hard to level up at the beginning. At the beginning its easy, and then it gets harder and harder the more you level up because you have to get more XP.
NARUTO20FAN:
I just want to get a few things clear:
1) The thing silverarch said was not funny.
2) You seem to be one of these persons who don't have a life outside the internet and therefore spam forums and comment sections to be seen... Please stop that. People will just hate you. Go and get a life, stop making stupid comments. The world isnt as bad as you think.
