First of all, what is the Siege Workshop? Do you eat that?
It is a unique haud building, replaces the European Artillery Foundry. The following units are created in this building.
It costs 200 wood, and is available in fortress age, but is normally used in Industrial nothing else.
My suggestion, enable building from commercial age, allow RAM to be a unit of commercial age. (Come on, it’s not cutting edge technology). Adjust its HP and attack accordingly, that way the unit will be more useful, it should be the most useless unit in the whole game.
Increase the cost of the building to 250W and adjust its exp for profit.
Can this be polished? 15% maybe you see? Although I must admit that 10% is acceptable.
And the following is what I would like us to discuss. The light cannon must be in Industrial? If you ask me, maybe , I mean, a very similar unit very famous here, called Flaming Arrow, is available in Fortress age for Japan, even though they have Yabusame, which in theory should take care of those things. So why the haud cannon must be industrial?
The Haudenosaunees in my opinion, are the civilization that has it more difficult to deal with artillery. Recent buffs for arrow knight, huaraca and the good army lakota make it less difficult to take out artillery. The hauds depend on the Kanyas and Musket Riders, who most of the time to eliminate artillery must launch suicide attacks, if the haud economy were good enough to replace the losses I would not complain, but that is the reality.
So I ask you, what do you think? For me, the cannon should be moved to the fortress age, but with a reduced range of 28 and maybe a little less HP.
