1. Don't engage in fights where you have a 1 unit army and he has the counter to that unit in your army (huss vs. pike and jan vs. skirm/pike).
2. retreat villagers to a safe location as soon as they are threatened by your opponent's military.
3. Allying with the iroquois ended up being useless, and you could have made a trade route post for the same cost.
You did a great job when you used jan/abus/falc. Jans and falcs together are incredibly strong.
