Let us define the base mob def% to be PDR. eg. 0.4 for Zakum
Damage multiplier when equipped with a weapon with 30% boss dmg is 1.3
Damage multiplier when attacking a boss with PDR is 1-PDR
Total Multiplier when equipped with a weapon that does 30% boss damage is
(1-PDR)*1.3 -> 30% bossing
Similarly,
Total Multiplier when equipped with a weapon that ignores 30% boss pdr reduction is
(1-(PDR*0.7))
* I am still wondering about (1-(PDR-0.3)) as compared to (1-(PDR*0.7))
Solving for PDR where these are equal,
1.3 - 1.3*PDR = 1 - 0.7*PDR
0.3 = 0.6*PDR
PDR = 0.5
As PDR increases, 30% ignore def gets better, so for greater than 50% def, it's better to have 30% ignore target def.
( In this case Chaos ht, Chaos zak, pink bean and cygnus would satisfy this equation)
If your class already ignores some % def, call this SD (for example hero's enrage has sd 0.4) (SD <= 70% otherwise there are issues with this method - mostly that 30% bossing is always better)
Total multiplier with class sd and 30% boss damage would gives
(1-PDR*(1-SD))*1.3
Total multiplier with class sd and ignore mob 30% pdr gives
(1-PDR*(0.7-SD))
Solving these 2 to find a relationship between pdr and sd
1.3 - PDR*1.3 + 1.3*PDR*SD = 1 - PDR*0.7 + PDR*SD
0.3 + 0.3*PDR*SD = 0.6*PDR
0.3 = 0.6*(1-0.5*SD)*PDR
1 = (2-SD)*PDR
So eg. if SD = 0.4 (heroes), 1 = (1.6)*PDR -> 62.5% def is the minimum before ignore def is better.
If we have threaten then it would have
total sd = 0.61 1= (1.39)PDR => PDR = 0.71 , so a pdr of 71% would be needed to be better than a 30% boss dmg weapon
what happens if sd = 0.2 for archers, then we have 1 = 1.8 PDR => 55% PDR and above would be needed for a ignore weapon 30 to be better.
