Hello
I’m French, so I try to explain my rule idea, like I can. Sorry for my English…
I have bought a French book of pathfinder edition. You have made a good job to upgrade the 3.5 edition. Congratulation!
But I have one regret. With pathfinder edition there is one point that be not resolve for me. The Armor Class. So I explain.
The BBA (Bonus Base to Attack) increase with the level, but not the AC. So if you are a 4th warrior or a 20th warrior, with no armor and no magic item, your AC is 10 !
I think that the armor must be up with the level but not like a D20 modern system. So have one idea. Suppress the dexterity bonus to the AC and replace it by the AGILITY bonus.
This new bonus AC category is a combination of the dexterity bonus and the BBD (Base Bonus to Defense). This BBD up by one when your BBA up by 3. This AGILITY bonus run like the (ex)Dexterity bonus. He is limited by armor limitation and disappear in a lose dexterity situation.
I Resume:
AG = Dex bonus + BBD (+1 for 3 points of BBA)
Example:
I am a 15th fighter. My BBA is 15, so my BBD is +5 (15/3=5). My dexterity is 14 so my bonus dexterity is +2. So My AC with no armor is 17 (10+5+2). If I wear a chain mail (+6/dex limit 2) I have 18 AC.
If I am surprise in a battle, or lose my dexterity bonus with no armor my AC is 10, with my chain mail 15. So the armor conserves the monopole of the good protection, but if you can accept the risks, you can make a warrior that he fights with no armor.
So, has you can see, this rule don’t destroy the stability of the game.
With this rule, you can add these Feats:
Unarmored fighter
When you fight with no armor, your AGILITY bonus is increase by +2.
Agility of the warrior
Use your DV instead of BBA to calculate your BBD (+1 for 3DV).
So, What do you think about all of this ?
