Heiho,
according to some PvP testings Necro's BA is in 1.10 damaged before both physdamred modificators (a change from 1.09). Because of the low damage the Defiled Warriors do with their normal attack, it is all absorbed by your 50 absolute damage reducing via Amulet and Circlet, once your BA is crushed. But they _do_ hit you, so the duration of your equipment suffers.
Can't give you a clue what's up with the exp oddities.
