I have to agree on this - voulgiers seem to be weak halberdiers, and seeing that regular halberdiers aren't that great anyway...
Besides, France has the best horses there are. And basically, that's all they need : anything that has "spear" or "pike" in their name, you let the footknights and/or Xbows butcher. Anything else, you charge right through with your horses. It's no bug that France has both Noble Knights and Chivalric Knights with the same stats : you have twice more cav than anyone else. Factor in order knights (templars/hospitalers), and you can pretty much steamroll any army, be it on foot, on horse or with bows. See my sig for further details :)
Voulgiers can theoretically hold a horsecharge if in spear wall, but then again so can your own cav...
