As far as I am aware the mechanic (westernisation) is there to be taken full advantage off. Plus its not something easy to pull off. So whats stopping Russia from Westernising? The need to form Russia thats non stop wars and AE that prevents you from doing it. Not say the least from random events and all the monarch points. On a side note, you do understand that you condradict yourself? Russia either will westernise or eat everything not both. You cant do both at the same time. Neither the hordes do but thats a problem of strategy and timing.
Except your forgetting three things.
1: Russia does not need to westernize. Infact, I recommend against westenizing as Russia. Yes, lategame Eastern cavalry sucks but cavalry is completely irrellevant after tech 12. Eastern Infantry is nearly on par with Western infantry, tech 30 Russain Mass has 52 pips while Jagers have 54 pips, Drills have 54 pips, Mixed Orders have 57 pips, and Napoleonic Squares have 60 pips. All of those are western tech 30 infantry.
2: The Hordes have to reform then westernize. Reform requires that either Economic, Innovative, or Administrative idea groups be completely filled, 90 legitimacy, 3 stab, and 200 admin points. Upon enacting Reform, Hordes lose their government bonuses, get upgraded to either Chinese or Muslim tech groups and unit types depending on their religion, and take a -5 stab hit and lose -200 admin points.
3: All other non-western tech groups have to westernize in order to fight against Russia. Ottoman infantry caps out at 38 pips, Muslims cap out at 37, Indians cap out at 32, Chinese cap out at 28. All of those infantry types will get steamrolled by Russian mass infantry. Thats before you consider the technological advantage that Russians will have over Asians, because Chinese tech group has -60% tech penalty and Indian tech group has -50% tech penalty.
And why only human players can do (now it became 'reasonably difficult' whereas it was impossible and a ridiculous notion....) it? I still havent heard a convincing arguement.
You have to get adjacency with a Western country. Where does one find a western country in the Steppes?
Seriously, if I have to school you on basic shit like this, it makes me start to question how much you really know about this game, and weither you give a damn about balance and are not just here out of some patriotic duty to the motherland.
Same can be said about Castille, but none is complaining about Castille....
What strength does Castille have? All those overseas colonies that Castille is getting nothing for because they are all overseas colonies?
