I hit corrosive armor (which is supposed to limit inc damage to 3% for 10.8 seconds) today in cyrodil, and it did nothing. In my combat log it is active, since it did some damage on the other players, but it did nothing to mitigate damage, I took full damage from the other players in all forms (direct, cast, bleeds etc) and died before the corrosive armor should have expired
4 GOs, and General, and bunches of prefects etc-- all classes...I've wasted a lot of time in PVP over the last 8 years
