Well, you need to try the Sengoku scenario on a higher difficulty level... 
Here the barb uprising creates 24 Ronin units per barb camp. If I remember correctly, these little suckers have 4 attack, 3 defense... And there are many pre-located barb camps on the map, which you can't possibly extinguish all in time (and even if you do, they seem to respawn quite quickly...)
Funny story: we played a multi-player game with the Sengoku map back in 2009. Calis, a very experienced MP and HoF player, went on vacation and asked Chamnix (a very experienced GOTM champion) to be his substitute, so the game could continue during his absence. On his very first turn as substitute, Chamnix parked his Daimyo unit (the King unit of the Sengoku scenario, meaning, if you lose it, it's "instant game over."..) next to a harmless looking barb camp. On the same turn, I entered the next era and triggered the barb uprising... And to everyone's surprise, the mighty Calis Empire got eliminated interturn...
BTW: the Sengoku map is also one of the scenarios that suffers from the river bug, as we found out during that MP game: quite a number of tiles, that were clearly adjacent to a river, nevertheless got neither the commerce bonus nor the fresh water. (I was very surprised to find, that a town I had founded there, still needed an aqueduct...)
