The initial damage of your DoTs ignore the physical resistance so it's still benefitting your abilities. And yes, Noxious Breath and Venomous Claw have a direct damage component to them so it's not 100% worthless to you. DK is direct and DOT focused.
Once upon a time it did. Then ZOS invented Onslaught and everyone started running that new toy. We also had a patch (Spellbreaker, if I remember correctly) where DOTs were doing insane damage. Somewhere along the line ZOS decided that 100% penetration on DOTs was too much in PvP. To the best of my recollection this was because people complained about Onslaught. I do, however, remember distinctly that ZOS nerfed Corrosive Armor at the same time as Onslaught for "consistency", even though no one ever complained much about the former skill. Of course the DOT meta is long gone and Onslaught has fallen into disuse, but ZOS never ever just roll things back exactly to the way they were before.Extinct_Solo_Player wrote: »Corrosive armor, why does this ultimate not affect our core damage abilities, which are mainly damage over time? Doesn't make sense to only buff direct damage when the whole theme of the class is sustained pressure with dots.
