So, we have the endless coppermines. Which are limited to 3. Perfect.
However now we need more iron for example, because of the changes to epic adventures.
Maybe introduce more endless mines or such? Heck the less I have to rebuild tbh the better.
So even an endless stone pit or marble mason are things I certainly wouldn't mind seeing in the gemshop.
And as with the endless coppermines, just balance it by putting a limit on them.
I certainly wouldn't mind a few endless Iron mines. And no it will not make artic pointless as we will need a lot of iron now to get through epic adventures now that weapons have been removed from loot.
btw just realized marble and stone will be impossible as they are not setup the same way as Iron and copper mines ... my bad -_-. Still maybe something for BB to figure out? An item you can use to make it endless perhaps? Dunno I'll leave it up to you.
p.s. yes I am lazy and would like to have to rediscover and rebuild as little as possible at some point
