Mod Question: Offense v. Critical Damage

Depends on your CC.and whether you have CD primary on triangle.

1) No CD triangle (150% CD & 10% Offense vs. 180% CD)
Well the expected damage output of the former is 1.1 times the original one.

The original expected value for damage
= Base dmg + (CC × 0.5× Base dmg).

Offense mod make it 1.1×
so
= 1.1 Base dmg + (CC× 0.5×1.1×Base dmg)
= 1.1 Base dmg + (CC×0.55×Base dmg)

CD mod makes it like this
=Base dmg + (CC× 0.8× Base dmg)

Which is bigger?Situational

Offense mod case - CD mod case
= 0.1 Base dmg - (CC ×0.25 × Base dmg)
if this is >0, Offense wins. <0, CD wins
so if 0.1>CC×0.25
in other words, if your crit chance is lower than 40%, offense mod is better.
If crit chance is 40%: indifferent.
If CC is over 40%, CD mod.
But this is when your triangle primary is not CD

2) Your triangle primary is 36% CD
(186% CD & 10% Offense vs. 216% CD)
Well the expected damage output of the former is 1.1 times the original one.

The original expected value for damage
= Base dmg + (CC × 0.86× Base dmg).

Offense mod make it 1.1×
so
= 1.1 Base dmg + (CC× 0.86×1.1×Base dmg)
= 1.1 Base dmg + (CC×0.946×Base dmg)

CD mod makes it like this
=Base dmg + (CC× 1.16× Base dmg)

Which is bigger?Situational

Offense mod case - CD mod case
= 0.1 Base dmg - (CC ×0.214× Base dmg)
if this is >0, Offense wins. <0, CD wins
so if 0.1>CC×0.214
in other words, if your crit chance is lower than (100/214)*100%, offense mod is better.
If crit chance is (100/214)*100%: indifferent.
If CC is over (100/214)*100%, CD mod.
this is when your triangle primary is 36% CD
