Got it. Make Portugal a Musk Falc civ. Remove the Dragoons that pair well with Cassadors and Portugal can finally be a more historically accurate Musk Falc civ, like British (musk Falc), Ottomans (Jan Falc), Swedes (Caro Leather/Falc)…
Currently Portugal has a unique play style (though admittedly they have few options) and a military comp that handles differently than any other Skirm/Goon +art mix.
The problem with historical accuracy is that most of the European civs would be too similar because most of them developed similarly militarily speaking.
If I recall correctly it’s historically inaccurate for Germany not to get Musketeers. Same thing probably applies to the Dutch. And Russia didn’t fight with masses of poorly trained troops at the time the game is set in if I recall correctly.
The reason for the historically inaccurate gaps in unit rosters is to make the civs play differently. Admittedly Russia’s is based more on a stereotype of how people expect Russia to play I think. More examples could be added but I don’t feel the need to list more right now.
Deleting the Goon stuff from Portugal would make them less unique because they’re unit comp would look just like the rest of Europe at that point (except worse because Cassa+Musk is worse than Cassa Goon outside of treaty games for reasons I outlined Here ).
If you want a Royal Guard Upgrade for Halbs remove the Royal Guard Upgrade from their Musketeers and give it to the Halbs.
