France has to contend with England burgundy and Spain. Ulm is heavily insulated within the hre and a free city, the only way for it to be attacked is to have an ally who's war you join
It was meant as a joke that I took those specific two countries. All I'm saying is: there is not a single country that's truly equal to another country. Ideas are unique to each country, as are institutions, tech groups, development and access to trade goods.
The design of this game was never with winrates or balance in mind like it is in Starcraft or other competitive strategy games where if race/faction X has more than say 52% winrate it's a big issue. Now of course, that doesn't mean you should give country X +15% discipline just because. Which, granted, is what happens here with the info we have currently available.
This game has always had specific things that are considered overpowered though. If it's the Shogan vasal swarm, or the Mughals Diwan mechanic, those aren't 'balanced' as well.
I do feel that people are overreacting with the info we have though. For all we know is the Alhambra wonder tied to Sunni religion and Andalusian main culture and is it not shown in the tooltip because those parameters are already fulfilled. Would that be so different than forming the Mughals, which has easy access to 10 admin efficiency as well (and had it in 1.29 before the Admin efficiency nerf)?
Is having that admin efficiency so overpowered, ever since you could already stack to that max limit anyway, using formables like Sardinia-Piedmont and Prussia's mission tree?
Will it make it easier to get? Yes, of couse. Does it break the game? Well, it certainly might, but I'm reserving judgement until I can actually play the game instead of rioting here.
Does it warp multiplayer? Well, will it warp it more than Orthodox Religion? Or forming Prussia? Or Russia and their Cossack estate? Or even Ming which is usually banned? Now we have a lot of wonders that will be worthwhile going for and if your opponents let you, the fault is there. Or you can add another houserule, like there are already so many.
