Your broken English made it hard to understand.
Are you saying that you're level 38, and killing 5-10 mobs only yields 1 EXP? And then you and your friend in a party, you kill a mob and both you and him gets 1 EXP?
If so, that's normal. EXP is shared in parties.
Not that Hard to Understand really, all im saying is im trying to help my Friend Level up right, so We were Grinding mobs but since our levels are so far apart, If i Kill a Monster Around his level He gets full Exp from it ( lets say he gets 100EXP per kill) and i Only get 1EXP " thats not shared " and If i Kill a Monster my Level I get Lets say 300EXP From it and he Gets only 1EXP you get me, I just dont remember it being like that
