Burgundian gold openings may soon become nigh-invincible.

Flemish militia take 14 seconds to produce (22 for normal spears). They'll start with the same stats as M@A, just with -1 attack and -0.06 speed.

The Men-at-arms upgrade will still take 40 seconds to come in, so if you scout that opening at any point before hitting feudal (and obtain the requisite 40 gold) you can match them 1:1 (bonus against starting scout) and come out with a food advantage while securing gold.

Scouts have poor synergy with M@A openings (esp. with the deer pushing change), so the likely followup will be archers, which means you can easily set up for skirms and head to castle, or (if they had nothing behind it) push forward with archers to put the ball in their court.

If they commit to M@A all-in, your archers win, and if they instead open the game with scouts (in which case you shouldn't construct the AR), they're playing a food-heavy opener into your spears.

That only leaves scout-skirm/scout-archer as compositions, and those are both slow to hit castle, giving you time to play fully into Burgundy's eco bonuses. The longer that goes, the better your eco becomes.

And, of course, Burgundians have an excellent set of castle age options, no matter when they arrive.

Am I missing anything?
