-Remove RG Dragoon , Pikeman, and all Cavalry cards (except Riding School) and replace for RG Halberdier (Aventureiros) + Age 2 and 3 Crossbow + Halberdier cards.
Portugal never really used a lot of Cavalry, or had well renown Cavalry regiments, as the geography did not allow it. Dragoon cards also make much more sense for the British, which had their Mounted Grenadiers.
Though Pikemen were used, it was mostly for continental warfare, while Halberdiers were much more used in the Colonies, since the weapons are much easier to tranport on ships, than the very long Pikes.
It would also be interesting to have another Euro civ, besides Ottos and Russians, that does not have Pikeman.
Having a core of Age 2 and 3 upgradeable units + the Falconet, would also encourage Ports to play the earlier Ages.
-Remove Organ Gun, replace it with Falconet, give OG to the Brits, as they lack Skirmishers and it is their weapon in the first place.
Really makes no sense why Ports have an English weapon from the 100 Years War, but since Brits already have Longbows, it would fit them a lot more.
-Remove Colonial Militia, replace with a new “Old Arsenal” card, that allows TCs to train Crossbowmen (requires Age 2) and perhaps ships an Arsenal Wagon.
This is a historical reference to the Siege of Oporto, when Napoleon’s legions surrounded the city, and gunpowder run out, the defenders opened the aging Medieval Arsenals and used Crossbows to great effect, fully managing to keep the French out, until the British disembarked the relief force.
-Replace several Mercenary shipment cxards with more appropiate African, Indian, Chinese and Japanse units, instead of the muslim units that Portugal did not actually employ. Remove Barbary Coast Revolution from Portugal, and give it to France, which at least controlled Algeria.
A lot of these are plain wrong. Portugal fought the Mamelukes and Barbary Corsairs, not ally them.
Instead, Portugal used numerous mercenary forces from elsewhere in Africa and Asia.
Replacing Mamelukes with Mahouts, and Barbary Corsairs with Ronin or Rattan Shields, would be much more accurate, and clash a lot less with what other Euro civs get.
-Change Logistician to Musketeer, Caravel and Culverin + 1 Range.
This would actually make Portuguese Logistician a choice for long term games, be historically referencing to a good degree (early adoption of Breech Loaders, alloyed ammunition for cannons, gunpowder overcharge for extra Range), and cover for Ports lack of Ship stat cards.
