No real new player needs the double xp, first of all they dont have the money then to get their weapons build and need to level with storebought shit... oh yeah that what ll keep the playing... till /50 with storebought... you should see how happy are new onces when they get their first weapon build.
Also they dont really care bout the leveling speed, they are running around and look at things, even when its not that good for xp/hour.
so stop whining when you already leveled one character you should know how to cap at least 1 character per weekend, otherwise read again from the top
