Players are given the ability to choose between converting ores into 2 main icons. (Jewels, coins) they can convert ore into jewels or coins which will be easier for speeding up the process of the wait time...
that would unbalance the game.. only players this could benefit would be brand new players with very small caps, and the top players who have no buildings left to upgrade. I have to disagree with this idea for those simple reasons. :/
