I am now getting into the bread and butter of this mod, the affixes.
 
Armor
With the new stat Vitality stat no longer giving an armor bonus, this now needs to be obtained through affixes.  I am thinking of giving an armor bonus to every chest piece with in it's Unittype that spawns every time (with a 0 slot).  This affix would scale with item level.  The bonus I will list below would be the % on a level 100 item

Here is what I am thinking roughly

Legendary Heavy Chest Armor: 400% armor bonus
Unique Heavy Chest Armor: 300% armor bonus
Magic Heavy Chest Armor: 275% armor bonus
Normal Heavy Chest Armor: 250% armor bonus

Legendary Medium Chest Armor: 350% armor bonus
Unique Medium Chest Armor: 250% armor bonus
Magic Medium Chest Armor: 225% armor bonus
Normal Medium Chest Armor: 200% armor bonus

Legendary Light Chest Armor: 300% armor bonus
Unique Light Chest Armor: 200% armor bonus
Magic Light Chest Armor: 175% armor bonus
Normal Light Chest Armor: 150% armor bonus

Legendary Cloth Chest Armor: 250% armor bonus
Unique Cloth Chest Armor: 150% armor bonus
Magic Cloth Chest Armor: 125% armor bonus
Normal Cloth Chest Armor: 100% armor bonus

Should I do something similar with Elemental armor, with it favoring Cloth armor?


Also will be doing away with flat stat bonuses ie +50 to Dexterity and will be implementing a % bonus instead, ie %50 Bonus to Dexterity. 
- This will reward players for investing into stats
- Will help balance the game pertaining to stat bonuses and item requirement stats. 

Damage Reduction
- Should I allow this affix to spawn on armor?  Currently it just spawns on a socketable.  I really do not enjoy this mechanic.  Forcing players to "be required" to have these socketables to reach the 75% DR to survive kills variety and devalues all other socketables.  Simply putting them on armor as a random affix helps solve this issue... But it will become easier to get DR (which is good).  I could just make it a Legendary item only affix.  That way Legendary armor is a must have to survive.

So are you are proposing to have all armor with 0 armor and just use the DR% stat?  At that point, there is no need to use DR as a dropable stat.  A player would need more assurance for protection than having to rely a random DR Drop.  Without DR on all armor at all times, it leaves the player extremely vulnerable.

Ok, I will try this out.  It sounds very interesting and will probably work better than armor value for sure.  It should be easier to work around and balance as well.

I have Heavy, Medium, Light and Cloth armor so I am thinking along the lines.  It won't be very hard for me to implement this.  Note++ ftw and then just creating an affix that controls the DR for the armor.  Easy peasy.

Here is what I am try first
Heavy 50%
Medium 40%
Light 30%
Cloth 20%

Question

Should cloth armor be able to max out to 75 DR?  If I allow DR to spawn randomly on items or on socketables, all armor unittypes will be able to max out DR.  That would pretty much make no difference between the unittypes DR% wise.  The only difference would be stat investment and affixes I choose to spawn on items.  I don't think that is enough.

I think I should eliminate the DR from random spawns and socketables and completely control it on armor since it will now essentially become the new armor values.  For variety I can have the DR affixes spawn in a range such as 45-50 so a player won't always get maxed out.  They would still have to work for max DR or just really lucky.

Heavy Armor Maxes
75% Physical DR
50% Elemental DR

Medium Armor Maxes
65% Physical DR
60% Elemental DR

Light Armor Maxes
60% Physical DR
65% Elemental DR

Cloth Armor Maxes
50% Physical DR
75% Elemental DR

This will should help differentiate between armors.  Otherwise everything will pretty much feel the same.

I could also break the Physical DR and Elemental DR to spawn on certain armor types.  There are 7 armor types, that's a lot to split 50% across.

Physical DR Items
Chest Armor
Pants
Helmet
Shoulder Armor

Elemental DR Items
Boots
Gloves
Belts

Maybe I can have shields reflect damage as their bonus and leave DR off of them.

It's the small details that make a good mod great.  I like your idea of adding small bonuses on rings, amulets and belts.

Shields using block is good enough I agree.

Looks like I have some math to do.  I want these to scale to level 105 items.

Second the motion on the split physical and elemental DR. It just makes sense to me (which means it should make sense to other non-technically obsessive players )

Sounds good, RnF.  What kinda problems was it causing?  I might attempt it in the future.

The biggest issue I can see is breaking skills for a lot of classes.

Hi RnF! Can you expound this point a bit more pls? Im starting dreaming up some new skill trees for the "classless character" idea of gytfunke and I think it would be important to know what the issues are so that the design could still use this DR armor idea.
