Can it be something like this :
(unit.h)
// player or player's pet resilience (-1%), cap 100%
uint32 GetMeleeDamageReduction(uint32 damage) const { return GetCombatRatingDamageReduction(CR_CRIT_TAKEN_MELEE, 2.0f, 100.0f, damage); }
uint32 GetRangedDamageReduction(uint32 damage) const { return GetCombatRatingDamageReduction(CR_CRIT_TAKEN_MELEE, 2.0f, 100.0f, damage); }
uint32 GetSpellDamageReduction(uint32 damage) const { return GetCombatRatingDamageReduction(CR_CRIT_TAKEN_MELEE, 2.0f, 100.0f, damage); }
instead of this :
// player or player's pet resilience (-1%), cap 100%
uint32 GetMeleeDamageReduction(uint32 damage) const { return GetCombatRatingDamageReduction(CR_CRIT_TAKEN_MELEE, 1.0f, 100.0f, damage); }
uint32 GetRangedDamageReduction(uint32 damage) const { return GetCombatRatingDamageReduction(CR_CRIT_TAKEN_MELEE, 1.0f, 100.0f, damage); }
uint32 GetSpellDamageReduction(uint32 damage) const { return GetCombatRatingDamageReduction(CR_CRIT_TAKEN_MELEE, 1.0f, 100.0f, damage); }
I really really don't know if it's the right way, but it's after some tests it seems to work.
