Well, to be honest we should wait for 1.8 before continuing this topic.Well, whether one agrees with it or not, I'm pretty sure they DO want Russia to approximate its historical role in, at least, some games. Given that the "edge of Europe" majors like Russia and Ottomans have gotten some nerfs along the way, giving those nations some easy punching bags/land grabs may be one way to keep some sort of "balance" among the great powers. And perhaps that's easier than tweaking the various interactions among Austrian/Ottomans/P-L/Russia.
Or maybe I'm reaching.
To be fair, they appear to be coming a long way toward making much of the RotW interesting, semi-realistic, and reasonably entertaining to play. Maybe Hordes will come eventually? Maybe it's just not worth it to them? Or maybe getting the rest of the game to work well means some region needs to be victimized ahistorically, and Central Asia gets to be it?
In EU4 base tax means everything (and when the base tax is similar, lucky nations > shock > everything else). The rest of the world has just gotten a massive base tax buff and as a result the game dynamics will be wildly different.
I expect for example that the Berbers will hold their own much better against the Iberians, India will probably push back the Red-Tide-of-Doom, pardon me, the Red-Timur-of-Doom, if a strong enough power rises there before the Timurids swing around, etc.
Same for hordes, even their lands have received a base tax buff.
So as far as 1.8 is concerned their relative strength has increased, at least for the first 100 years or so. And who knows, maybe they'll grow so much in that time that even the dumb, non-reforming AI won't be eaten whole by Russia.
I hate it that Paradox completely removed foreign core recruiting trying to kill the option of staying unreformed for players, but until they revert the change or do something better I'm going to test hordes + marches -> this should work somewhat as a replacement. Want to bet that if enough people post huge horde empires using marches, marches will be restricted to higher tech groups? (I really, really, hope they're not restricted already! :wacko
