Do you realise the increase in DPS Fujitsu

So, first, what do you mean by Strikethrough ?
A ) Is it a net - X % to the mob's mitigation (mob has 40% mitigation, net reduction of 20% means the mob goes down to 20% mitigation)
or
B ) would it lower by X% the mob's mitigation ? ( lowering meaning the mob would go down to 32% as 20% of 40 = 8.)
Second, to show the increase in dps both would made here's the formula.
Lets keep the same numbers :
M = mitigation of the mob
S = Strike through value.
D = Base DPS
F = Final value of DPS
X = Percentage of increase in DPS
Since we're talking of percentages, we'll say a monk has a base 100 DPS, that's before the mob's mitigation.
So, when a monk hits a mob with 40% mitigation, his DPS is 60.
Formula :
F1 = D - (D * M/100)
F1 = 100 - (100 * 40/100) = 60
So, without strikethrough, a monk would have a base dps of 60 (that means actualy 60% of the dps he would make on a mob with 0% mitigation).
So now lets study option A.
We still take 20 Strikethrough. (so S = 20)
So, the final value of dps would be 80 (that is 80 % of the dps he would make on a mob with 0% mitigation)
Formula :
F2 = D - (D * (M-S)/100)
F2 = 100 - (100 * (40 - 20)/100) = 80
That means an actual increase in DPS of 33.33%
Formula :
We take F1 = 60 (Dps without Strikethrough) and F2 = 80 (Dps with Strikethrough)
X = (F2 - F1)/F1 * 100
X = (80 - 60)/60 * 100 = 33.33333 (going from 60 to 80 makes an actual increase of 33%)
Now lets take option B
With this option, a monk would have a base dps of 68
Formula : (F3 meaning the final DPS after mitigation of a monk with Strikethrough 20% calculated with option B)
F3 = D -(M - ((S/100)*M)
F3 = 100 - (40 - ((20/100)*40) = 68
That would mean an increase in DPS of 13.33333 dps
Formula :
We take F1 = 60 (Dps without Strikethrough) and F3 = 68 (Dps with Strikethrough)
X = (F3 - F1)/F1 * 100
X = (68 - 60)/60 * 100 = 13.33333 (going from 60 to 68 makes an actual increase of 13.33%)
So, in my very humble opinion, a buff that would add 13.33% raw dps on a mob with 40% mitigation (and we could get numbers from various zones, but 40% mitigation seems realistic for higher end stuff ?)
Give me actual numbers for mobs mitigation, especially for raid stuff, and i'll give you the raise in DPS.
13% is imho already way to much. That means 13% plus the actual dragon stance that adds like 30% no ? (meaning a global increase of 47% dps compared to a monk with no stance)
Imagine the imbalance with the other two paths ?
