Before I say anything, just so you know I was a colonel in Vanilla before decay came in and I haven't played enough people in TWC yet to actually gain that much rank.
Anyway, in Vanilla cuis spamming is asking for a loss. Any average DM player should be able to defend against a pure cuis rush purely because it's so counterable. against every single civ it is easily beaten because of either Dragoons, Ruyters, or the occasional russian player with halbs. The only civ that doesn't have any of those is Otto, but nobody is stupid enough to play otto in a 1v1 ESPECIALLY against a rushing civ(solely because they are a very slow startup civ in DM, very opposite of Sup I might add). But honestly in vanilla you would want to send 3 vils or so to make a forward base, make stable, a few barracks, and a couple towers, and maybe an artillery foundry. The villagers that are back should make a church and houses and trained villies should make military buildings at the town. And you'd probably want to do about 25 cuis and 100 skirms, leave the rest of the population open for training villagers.
But in TWC it's a pretty easy win. Because of thoroughbreds, 10 CDB card, and French economy, its simple to have an efficient rush of cuis and skirms while building up the powerhouse that it is the French eco.
But personally you shouldn't do a pure cuis rush, because you will be labeled as a fag and nobody will play you(word spreads fast in the DM world wheres theres only 30 players), and it's a better idea to add in skirms to the mix anyway.
EDIT:@zimecki: Nobody should ever make a pure halb army especially against French, because of Volts.Are you considering the fact that its probably 75 halbs and 75 ruyters(so all your units get the chance to attack, to many melee units and some will be behind the lines not being able to attack) against 40 cuis? Not to mention in treaty the Dutch get two extra banks thats about 8 more villagers?(correct me if I'm wrong, I'm not an expert with numbers). Even against CDB's, 30 more population space does craploads more than you could ever imagine in games where a player should have a full population army out.
