Lucky trait: All units are +25% to Accuracy and +25% to Dodge. Imho it is a bit thick for 1 point. Now units get only 1 accuracy per level. So +18 Accuracy from start is huge. Moreover +25% to Dodge leads to well-known exploit: Lucky + Fortify + Blindness. Other 1-point traits can't compete with Lucky: Tough, Warrior Caste, Civics, Quick, Warriors, etc. Imho Lucky needs some balancing.
