do some changes to those upgrading stones we get from ladder or from grid tasks. Give us an equal ammount of each every day(well this happens already on US servers for ordinary upgrading ones as a reward for completing plunder task) or give us possibility to exchange them for other kind in the market. For instance I have Silver(bound) over 1000 and Crystal(bound) 300. I would like to have more crystal and less silver. You can add a function in the market where we can exchange those materials.
