See the above. My arguments would have been appropriate for a nomadic society. If Enlightenment-era Hordes were sedentary people, then there is no reason for them not to have access to the Development feature.
Oh, and please, don't make assumptions about my thoughts or my character. We already have enough self-righteous gits on here.
The Golden Horde (and the Crimean Tatarate) actively tried to conquer eastern europe. The result of these attempts at conquest in my country's region (Moldova) was the building of trade roads to the east from major local trade centers. They also built turkish bathouses, mosques next to christian churches(they didn't destroy much, as it was unprofitable) and developed manufacturing centers for merchandise that was too costly to carry around, and easier to produce locally. I'm not sure how much more civilized my region had become as a result, but it certainly grew more prosperous due to mutual exchange of goods and developed infrastructure (I'm thinking production and trade in EU4 terms). I don't see a reason why a horde wouldn't be able to raise development. It's just that they did it on the border or in conquered regions, not in home regions (as large metropolitan areas akin to the western ones were uncommon). Of course this varied from horde to horde, but generally speaking they were countries like many others.
They didn't have trade guilds or craftsmen's guilds, but then neither did many of the eastern countries. In fact one of the first (and only one around) universities in orthodox eastern Europe was established in 1632 in Kiev(the province, not the city). Education of the general populace and elites is usually linked to a level of socio-economical thriving, yet economy in terms of production, base tax(agriculture),trade and military manpower has nothing to do with formal education. Hordes had different ways of making money and recruiting warriors. Extorting money(tributes) and trading were the major ways they got their cash.
A horde overhaul mechanic would be nice, but not something as stupid as implying that they weren't capable of developing their economic standing in the regions that they controlled.
