I forgot to take the age 5 upgrade into account. I thought the SM got +175 attack in age 5 to make up for it scaling off of age 3 stats but I guess that is only for the building attack. I guess it would need +37.5 attack in age 5 to have the same dps vs infantry in age 5 as an uncarded Bombard.
The SM does get 5% attack from a Jesuit alliance tech and 5% hp/attack from an Oromo alliance tech as well as the passive healing from the age 4 card which is hard to quantify.
I don’t think a shipment has to be 1k res or even above 900 res to have decent utility as an age 3 shipment. Just to name a few shipments, 2 flaming arrows is only 800 res and 2 gatling guns is only 700 res while both are considerably worse both buildings. There are situations where people send those shipments. 8 regulars is only 840 resources and people send that. 4 mamelukes only gives net 600 coin worth of value and it is still a really good age 3 merc shipment. If the cost of the SM got taken down to 900 or even 850 it would still be more resource value than all these shipments that are still used in age 3.
I think in age 3 utility matter more than the cost. If it cost 100 influence but had good utility, it would be a good age 3 shipment. If it cost 10,000 influence but had bad utility it would be a bad shipment. For my purposes of sieging buildings with some anti-infantry capabilities, I think it has decent utility.
I did not realize the los was that low. I think it does make sense to buff it in age 3 by +2. Flaming arrows and siege elephants both have 34 los with the same range so 32 los probably wouldn’t be game breaking. It would also mean in age 5 it would have the same los as a mortar which would be neat.
I think giving it 1.5x vs infantry would be too much. In age 4 it would have more dps vs infantry than every other heavy artillery except the original heavy cannon where it would only have 6% less damage while being 88% better vs buildings and having more potential aoe. It would make the SM the second best heavy cannon vs infantry while being the best vs buildings and having more range. I think that is too many perks for a heavy artillery unit especially if it is coupled with a cost decrease. Maybe if the building damage got nerfed the infantry damage could be buffed but I personally like the design of having higher building damage.
Maybe the unit could get +50 infantry damage in age 5 in the same way it gets +175 building damage so that it could keep up with the dps of the great bombard in age 5 coupled with a cost decrease (accompanied with some treaty nerfs)
