but that update would take time and effort and balance if course
i think that upgare should take SKILLS not money.
actually make endgame dunegons gives stones will actually make people do contenet+make them work for something.
if will be my server i will put U70 stones ONLY AS CC 150 REWARD(5 random u70+1 white all stones binded)
this will be a system that will work.As the game is now is for make money,like original game.The logic of this upgrade is make you waste money on it,not effort,just luck and money
and ofcourse with whitestone no downgrade,so who like to bet can risk,who wanna do it safetely just farm white and try
also daily quests for white stones and U70 pure will help.
Anyway the major problem is the "broken" card and the horrible rates of sucess and drop rate of stones
