The revised Joudan progression will look like this:
Joudan no Kamae: Sustained stance, no stamina cost, prevents use of armor, only usable while wielding a single weapon. Decreases attack speed to 35% of base, increases critical chance to 60%, increases all damage by 10%, increases attack (chance to hit) by 25% sets defense to 0.

1: Shodan:
Joudan: +5% speed, +5% all damage
2: Dan:
Joudan: +5% attack, +10% speed, +5% crit chance, +15% all damage
3: Shogo:
Joudan: +10% attack, +5% speed, +15% crit chance, +30% all damage
4:Kensei:
Joudan: +20% attack, -20% speed, +35% crit chance, +50% all damage

This means at the kensei level, the Joudan fighter will attack at 35% of base speed, and have a 60% greater ability to successfully hit opponents over Chuudan and Gedan users.
