I agree, I commend the effort, but I think what was done here has further actually weakened Poland. Russia will benefit more from the boost to Ortho tech group than will Poland. I think the tax values were fine without so many tax value decreases through events. Manpower boosts were good, however a boost to Galicia should be included, as at least during the time of partition I know, this was the most populated area of the country.
My biggest fear however is the new tax collecting system. Poland is absolutely loaded with non culture/non religion provinces, especially post-inheritance. Even pre-inheritance Poland has Podolia and Danzig. Sooo, if we make it necessary for tax collectors to be in, for taxes to be collected, Poland is up the creek without a paddle. The revolts could get a little iffy at times before, just simply due to non-religous, non-culture, and the usual 3 religions within the borders, throw a tax collector in the mix and the Ukrainian and Russian provinces are gonna be spilling over with pissed off peasants.
And while its all fine and good to just not put tax collectors in, in the first place. Russia can, and the Ottomans can, and above the capacity of both of those is Sweden, at least in their culture provs, which for both of them are much more extensive than the Polish/Lithuanian, so we have Poland with a large tax reduction she didn't have before in comparison with her rivals. MM made a good suggestion about recieving a certain minimal percentage in your core provinces, I think he said 50%... I'm not sure if this could be a good alternative or not. And even still Poland would be losing out as the eastern provinces of the Ukraine, Odessa, and two of the Russian provs she inherits all aren't cores. In fact with the Ortho tech change, i'm not sure if Latin in itself will turn out to have the effect it did before in keeping her stronger, longer... Anyway, it will all have to be play tested, and this is all speculation at the moment. However i'd be interested in what the thoughts of others would be.
