I never said it's healthy for Portugal and Spain to struggle. In fact, I created a thread describing it as one of the biggest problems of the current patch.
It does matter who's the stronger one because dev is just one number and not the only relevant thing to look at.
And them sitting in #2 or #3 of the GP list still doesn't mean they're strong.
The patch didn't change much about Russia itself. It's surrounded by Horde and Novgorod. Everything can beat that. Has nothing to do with railroading but Horde nations played by the AI being weak in general.
Your focus should lie (if that's really an issue for you) on making Horde nations more effective.
Not on nerfing Russia.
So...Muscovy gets a bunch of easy provinces which increase the development of the Urals region...and the result is that Muscovy has a bunch more development and can trash everything. The solution is to...increase the amount of development of the hordes? Then increase the development of PolLith which was taken away a year ago because it was overdeveloped? Then increase the development of the Middle East to cope with the increased development of the hordes? Then..then...then...
That's textbook power creep and it's becoming a real issue. I have a better solution: get rid of the extra development that was added in 1.22 because it makes the region ahistorically overdeveloped in 1444 and causes the current issue in eastern Europe. The AI isn't bad at playing hordes in particular -- it's bad at playing against much stronger enemies.
Novgorod and the hordes used to survive much longer and sometimes even win from time to time. I don't have a problem with Muscovy becoming the regional power -- but I do have a problem with the entire region collapsing in 1450.
