This game us true PTW as there is not way to farm gold even in tiny increments. if you need an upgrade to keep playing the only thing for you to do is wait days for enough daily drops so that you can move on.
Be sure you are right justchad... It will be done, but it is not the now-now thing we will do. As you can imagine, it is a real pain in the @$& to combine the design on different platforms (cause as you already know, the game is cross-platform and you can use your progress in any device at any time).
