2. Do you play the mirror class of the class in question (or at least the same archetype)?
3. What perspective do you speak from? What is your experience with the class in question (be that playing the class, or playing against it)?
4. Your feedback
It will give substantial damage increase not only against heavily armored targets, but against all targets, as said post above. You can change it from physical to any other type of damage though, so it will affect armored targets more than light armored.
Same as previous thread - end goal is not stated, how team want to see WL? As I see it now DD class it is not meant to chase tanks, all it's kit including pounce looks focused on penetrating backlines and harasing healers and rdps (and with this buff WL would be able to do it better, cause of armor ignore, but still can't see any insentive to go for frontline engagement).
