Iron golems would destroy the iron economy, this is why they aren't implemented in the first place. I can move towards implementing other spawners though that don't give off too op drops.
Nah, I think that the cobble Gen should get the buff, so that ranks don't control all the iron supplies.
I would love to see the gen buffed, but a basic gen would still take forever to get a piece of iron. Maybe add 1 piece of iron to daily?
Until the upgrade and while profit shops are still in operation, I don't see any point in trying to balance things on Eco. While you can make $200,000 on profits shops per hour, it essentially means you can buy over 300 iron per hour from /shop. I understand that players might want to create their own wealth from their own farms and hopefully that's what the server staff want as well, and hopefully we will see that after the update.
At that point you move towards some of the whacko types of skyblock, while this skyblock tries to at least behave somewhat vanilla. If we added iron golem spawners, why not every mob spawner? If cobble gens were to get a buff as was mentioned before, that could work, however it would increase the amount of absolutely humongous server destroying wither powered cobble gen-inators
