I think some unit stats need tweaking.
- norse archers have ridiculously high defence (21); this is higher than any other unit in the game, maybe only bodyguards and full-plated swordsmen have better
- scots pike militia have strange low defense (10), lower than almost any other unit in spite of being armored in full-plates -- and in early game they are only unit in full plate armor
Tiberiu I'm not going to learn all this twaking now..check it out yourself
