dont nerf the gold, it was fine where it was at. if your doing this to force players to pay real money its not going to work. if the new players have no foot hold in the game and make progress at like, one weapon per year. your going to lose more cash and income. players are not going to just start paying money, it was already hard enough , this only drives them away. not even events would save it. the game is hard enough and the power needed for the new raids or dungeon is already high enough. a new player would never get there and thus would never spend cash to get there as they have other games to turn to.
do not do this, you will regret it.
