#112 Standardize Sunder Armor and Expose Armor

Status: Closed · Area: Classes & Specs · Warrior

A design proposal to make Sunder Armor and Expose Armor share one stacking armor debuff.

Current behavior

> This is a design proposal. I don't have beta access. The values come from the current Forever tooltips on Wowhead, and the interaction between the two is based on how they work in Classic Era.

Expected behavior

- Sunder Armor and Expose Armor share one debuff with a single stack pool, max 5 stacks, at 450 armor per stack. - **Sunder Armor:** unchanged, +1 stack per cast. - **Expose Armor:** +1 stack per combo point spent, capped at the 5-stack maximum. - **Refresh:** any application from either ability refreshes the duration of the whole stack, the way Sunder works today. - A weaker application never fails, and it never removes or replaces existing stacks. - At max stacks, either ability still refreshes the duration. Sunder keeps its threat, so tanks are never blocked. **Examples** - A Warrior applies 2 Sunders, then a Rogue uses a 3-combo-point Expose Armor. Result: 5 stacks (2250), duration refreshed. - There are 4 stacks and a Rogue uses a 5-combo-point Expose Armor. Result: 5 stacks (the excess is lost), duration refreshed. - There are 5 stacks and a Rogue uses a 1-combo-point Expose Armor to refresh. Result: 5 stacks, duration refreshed. - There are 5 stacks from Expose Armor and a Warrior casts Sunder Armor. Result: the cast succeeds, generates threat, and refreshes the duration.

How to reproduce

This is a design proposal, not a bug. The steps below show the current interaction, based on Classic Era behavior and the current Forever tooltips. I haven't verified them in the Forever beta.

1. Group a Warrior and a Rogue, both level 56+ with Rank 5 Sunder Armor and Expose Armor, and target the same enemy.
2. The Rogue builds 5 combo points and casts Expose Armor. The target now has Expose Armor (2250).
3. The Warrior casts Sunder Armor.
   - Current: the cast fails with "A more powerful spell is already active," so the Warrior loses Sunder's threat.
4. The Rogue builds 3 combo points and casts Expose Armor while the 5-point Expose Armor is still active.
   - Current: the cast fails, and the duration is not refreshed.
5. Remove the debuff, then have the Warrior apply 3 Sunders (1350). The Rogue casts a 2-combo-point Expose Armor (900).
   - Current: the cast fails. The two abilities never combine into more armor reduction than either one alone.
