Hi, How many Others think this will be a good move?
I Suggest we Have Endless Copper mines and they are Useful to Supply the Multiple Requirements for Copper its very useful as for Times when we are Unable to get to the Game then We have a Constant supply.
My Suggestion is the Iron is used for the Bookbinder Letter smith And Various Troops in the game that there should be Optional Endless Iron Mine.
P.s Maybe Drop the Titanium Ore to a Lower level also or put the Quest that Require At a Higher level (Requirement to Make things with Titanium Ore from level 30 ish with the Titanium Ore and Granite Come at Level 60?)
