When we consider the fact that sweden has 2 leather cannons which is equal to 800 res in age2, or other civs that get 2 falconets upon age3 which is 1.000 res worth, 2 Organ gun shipment is underwhelming for ports, it’s just 800 resources shipment and one of the worst artillery unit to use in age3, they only do acceptable engagement against land units and thats all, other than that they are just underperforming against most other units. To balance this issue, organs should have a better shooting animation for artillery wars or they could recieve a bonus damage something like 1.25 against artillery because they are far from being competitive in artillery wars. And the 2 organ shipment also requires a buff, it’s underwhelming currently. Best solution would be having 3 organ gun shipment in age3 for 250 coin. That way the shipment would become more competitive.
Organ Guns also miss the “lock fire” mechanic unlike falconets have, so that organ fire can be dodged while falconet fire can’t, which also is another disadvantage for Organ Guns
