Is your feature request related to a problem?

Only specific bosses using specific skills penetrate resistances and creates an inaccurate picture of the effectiveness of resistances on most other bosses. Penetration should only be added automatically into Boss Skill Presets. Guardians do not penetrate at all, nor do 5 of the 7 pinnacle bosses. This also creates issues when attempting to build around damage shift (e.g. Cold taken as Fire) due to the implementation of Penetration as generic pen, rather than element-specific pen. Damage shift intentionally bypasses the element-specific pen. There was also no rationale provided for this change in the update notes
