Does damage dealt to a unit reduce its might for combat damage purposes?

Ruling: Damage does not reduce might. A unit deals combat damage equal to its printed might value regardless of how much damage it has accumulated.

Sequence:

• Yasuo (6 might) attacks Volibear (9 might, deflect 2)
• Yasuo pays 2 power to target due to deflect 2, then deals 6 damage to Volibear
• Volibear now has 6 damage on it but still has 9 might
• During combat damage, Yasuo deals 6 damage and Volibear deals 9 damage
• Both units die (Yasuo takes 9 damage with 6 health, Volibear has 6+6=12 total damage with 9 health)
