The armor proc time is lower than ebon armor.
Level 76 arcane armor does not have haste. It adds only *2x dmg and 2x armor, where as ebon armor adds *3x dmg and 3x armor in PVE.
Man I really feel like this is a mistake :distress:, It seems like you implemented the PvP side of proc to the PvE as well. Please for god sake tell me its an issue that will be fixed. Thanks.
