[1.2.330] A gift most beautiful

Considering the significant increase on boss' PDrate/MDrate, those skills that ignore mob's defense will be more important

Hero: ignore 40% of target defense
Dark Knight: sacrifice ignore target defence (the description said W.DEF, need someone to confirm if it also apply on PDrate)
Paladin: 20% chance of ignoring target defense (if take threaten into account, it is an additional 30% defense ignore, this skill is godly now :p)
Mages: not sure, any skill that ignore MDrate? (Is the MDrate of all boss lower than PDrate?)
BM/MM: 20% chance of ignoring target defense
NL: ignore 15% of target defense
Shadower: seems no defense ignoring skill...
bucc: demolition ignore target defense (not sure if it is like the sacrifice? and is it spammable?)
corsair: seems no defense ignoring skill...


Personally I think drks may be the DPM king of PB bossing (70% PDrate) if sacrifice actually ignore PDrate?


Also I am curious about how the % ignore target defense works,
for example, if a mob's PDrate is 10
1. If a hero attack it, the mob's PDrate is reduced by 40 (become zero) or by 4(40% of 10)?
2. If a paladin or BM/MM attack it, the PDrate is still 10, but there is a 20% chance that PDrate will become zero?
