I'm bit of dissatisfied on the iron production chain. It seems the iron smelters are using too much Iron Ore and thats why the players are using millions of recruits instead of Militia and Soldiers. For example I have 5 level 3 Iron Smelters and they are needing total of 39 levels of Iron Mines. That means I have to keep up all 16 level 2 Iron Mines running 24/7 and still many of those have to be buffed all the time. That is insane if asked me and it will kill the interest to the Iron Production. It's so much easier to train 1500 recruits per day so why even bother to train Militia? They are not "that" good anyway. It's someway funny that I need 6 level 4 Copper Smelters just to produce enough Bronze to create enough Tools for the building of Iron Mines. I suggest the BB could change the needed Iron Ore amount per Iron Smelter level from 4 to 3 (for example). That would courage players to use more Iron instead of Copper.
