Nerfed: Mughals
I don't quite see why the Mughals would be nerfed. A) Mughals have never been a CU B) the decision the form the Mughals makes you an Empire. It may not be the strongest CU, but any CU is better than not being a CU.
But I don't get that nerf to Germany, it is already one of the more pointless formables (because realistically, if you own all those provinces you need to form it you won't get that many free claims), now you won't even get the cultural union. Because realistically, if you're on your way to form Germany you disband the HRE asap and will quickly pass 1000 development-
