[NON-ISSUE] Furious Might (Cleric)

Class: Cleric

Spec: Defiler

Context: If Fervent Strike (druid) active - Furious Might (defiler) give only a +10% Damage buff for the next 15 sec.
Without Fervent Strike - Furious Might give nearly the the full 15% Damagebonus for 15 sec.

Repro Steps:
1. Build a cleric with Defiler- and Druidsoul. Make Fervent Strike legendary. Put enough points for Furious Might in Defiler.
2. Cast any Defiler-Damagespell. Look at the damage or tooltip from the spell. Cast Furious Might and see the difference.
3. Use Fervent Strike legendary. Cast any Defiler-Damagespell. Look at the damage or tooltip from the spell. Cast Furious Might and see the difference (Fervent Strike must be active).

It seems that Unstable Transformation (20% Damage for 10 sec.) perform with 14.6% for 10 sec. if Fervent Strike aktive.

This is due to the additive nature of buffs.

All active buffs are additive with each other instead of multiplicative. Thus for each additional +% damage buff you have the net efffect of each will be seen as 'lower'.

It's 1.0*1.3*1.1*1.2 the way you think it'd work (Fervent+Unstable+Furious) which would be +71.6% damage.

Rather instead the actual math is 1.0*(1+ 0.2 + 0.1 + 0.3) = +60% damage.

Similarly Unstable which is +20%, by your math with fervent strike active the math is:
1.0*(1.0 +.2 +.3) = 1.5 or 50% additional damage. As opposed to 1.0*1.2*1.3 = 1.56.

Likewise, Fervent on it's own is +30% (1.3), so going from 1.3 to 1.5 is the ~~14.6% damage increase you see (other multipliers could be at play such as if you chose Diversify mastery)

In any case, could do more delving into the subject, but this is likely the exact same deal with the guild Sigil not granting 3% CP 'Bug' that was reported on. (The short is that it is indeed working as intended, but not as expected by players.)
