I had a brain-fart last night and made the following set - 4 x Hard wired with 2x System Corruption. The 4 piece Hard Wired, Chest and Backpack Talents worked flawlessly if a tad under-powered compared to my Gold seeker/turret build.
The System Corruption 2 piece Talent failed to work throughout a 30 minute trial in Foggy Bottom. Did a Hostage Situation on Bridge to right of Safe House, went up to a Territory Control and then onto Navy Hill Control Point. Not once did my armour move up from its damaged state despite multitude of kills with skills and weapons - Skill - Assault Turret and Cluster Seekers. Weapons MK17 and MK16.
Am i misunderstanding the talent? I am under the impression that 15% Armour on Kill restores 15% of my base armour on a kill.
