I dont know why ppl think this is to be true but it isnt, im currently playing on elmorelab C4 x3 and adena is x4 and quest is x4, totaly normal and fair enviroment.
Adena rate should always be higer than XP rate so the player has a normal lvling experience, not to get to lvl 20 and but top NO grade weapon, because top D is over 700k.
I have seen this error on many servers, i dont understand why is that... In order for this server to function eider change adena and quest adena AT LEAST to x4, or change the XP rate to 2 or 3, otherwise this will be unplayable, ppl will buy top D grade at lvl 30+.
