60% ABS (Damage Absorption) cap fucks over Heavy Armor
The average Light Armor build mitigates anywhere from 35% to 42% depending on the Phys/Elem numbers on armor.
Shirking Fort gives 20% Fortification.
That means cloth armor can easily have 55% to 62% damage mitigation when shirking fort is used without adding gems.
The fact that Heavy armor has on average 50% to 55% ABS means they can only effectively gain 5% ABS total and anything passed that is, “Rend Resistance,” due to the nature of how Fortify, ABS and Rend work.
My suggestion is…
Cap Damage Absorption based on Equipload
→ Heavy Armor - 70% ABS
→ Medium Armor - 60% ABS
→ Light Armor - 50% ABS
This does not negate any stat stacking, it just changes the scale of Effective Damage Mitigation and Rend Resistance based on Equipload.
