Gold Mine is an Unique building for the Celts. Its only build on gold deposit and here is the problem. Its work well in Skirmish, PVP and in most of the original quests but the new Celeste quests ruin it. Gold deposits most often placed too close to cliffs, rocks, other deposits or other objects making to build a Gold Mine there impossible. The map design looks good and natural with this "merge objects together" style but we loose an unique building with it. Celts has only 1 gold gathering upgrade while all other civs has 2 or even 3 upgrades. Loosing the Gold Mine by the map design make a drawback for Celts. Its not a game-breaking issue and they can make Caravans too (if its not forbidden by a secondary objective) but its don't solve the problem. What if we loose the training time reduction on a Babylonian Gardens? Nothing serious, just loose something what desinged for a civ. Suggestion: Check every Gold Deposits on every quests and fix them is definitely a lot of work and its ruin the map desing. So, its maybe easier to change the Gold Mine itself. #1 Gold Mine should be a special storehouse for gold only. + Build near to Gold Deposits as other Storehouses + Grants +50% gold drop-off bonus (similar when Priestess of Ra empower a storehouse) instead of Conservation - Can't garrison Villagers because don't need that - It will be a Treasury instead a Mine #2 Gold Mine should be build everywhere and give you a new source of Gold. + Can build everywhere + Give you a source of 2000 Gold as a regular Gold Deposit + Must garrison Villagers to mine out the Gold + Grants the original +50% Gold Conservation - Only 1 build limit. (For balance. Since it can be build everywhere, you can build it in safe area while other civs must go to the risky area for Gold if Caravans are forbidden by objectives.) I don't know which solution would be better but as a Celt player, I really want to see something about this problem.
