so portuguese and italians always were kinda similar in being a archer-gunpowder oriented civs with great water play and good cav, they both have wide tech tree, and similar way of be played and they used to have the same “good on water meh on everywhere else” theme
as for now, portuguese feels like just plain better italians. i do not think portuguese are OP by any means, if not maybe for some cheesy arena tactics that can be fixed in the next patch, but in general they have been improved in a massive way by just a few simple change, and i would like something similar to italian, since they are so similar.
consider portuguese have FU cav just like italians, missing hussar but having 20% gold cheaper knights, they have cheaper archer from the get go, so they already are a better archer civs than italians, and cheaper champs as well if needed. they have strong organ guns, and they have the same cheaper BBC than italians but with siege engeeneer…also feitorias, flexible eco bonus,faster techs, and all other goodies that make them simply plain better both on water and on land atm
Onlu also described pretty well the italians state atm and i think there is room for a buff.
some ideas by coping the last portuguese update would be move a bonus to a team bonus, like the 50% trade cart discount, maybe lowering it and making it affect all teams and then freeing place for a new imperial age UT that maybe makes condos available to all team and also make them a bit stronger for italians or in general as they are kinda meh
they could also have -100 wood on monastery to reflect their religious theme (the papal state)
or a feudal buff for archers (armor or speed are the only thing remaining looking at other bonuses for archer civs)
they could get SE tech
elitè geno shuld be changed completely since atm is wasted res, either making it much cheaper or give them a nice boost
not all of those thing at the same time obviously, but egenrally speaking, something can be done to them to make them more competitive and more interesting EVEN at the expens of a nerf on water if needed
