Here are a number of things to fix when it comes to oli :
Duelists : reduce the power of the tripple and double sonic slash cause we get 2-3 k dmg , make it so in a way it wont pass 1,5k .
Paladins: dunno if its true what Haizor sais but check it anyways
Overlords and Dominators : reduce theire P.def , they have hp drain , cp restore , self buffs and seals and most fighter and mage clases dont stand a chance against them .
We all know in L2 Off these characters are OP so why not fix them . Make this server different from the rest , i'm tired of seing top killers in olli duelists , paladins and overlords .
