Multiplicative or base increases

SnD/BF is multiplicative(ie 1.3 * 1.25 for a 1.56 total increase) so I would assume that Evis bonuses are as well.

Do talents in wow that increase damage by a certain percentage work off the base damage or stack multiplicatively?

IE. Improved Eviscerate + Aggression + DD 5pc bonus

(888+984)/2*1.15*1.06*1.15

or

(888+984)/2*(1+.15+.06+.15)

Either way I'm speccing from AR into coldblood once I complete the set, finally get to see some nasty 2600-2700 eviscerates on fully armor debuffed mobs.

My guess would be additive. Most things in this game are additive.

Example: Piercing Ice + Arcane Instability + Arcane Power.

And the way the MPQ's are formulated seems to lead to this directly. Phrasing it like "Apply Aura: Add % Modifier" indicates to me that that there's a variable somewhere which gets multiplied into your damage. Imp.Evis. will add .15 to it, and so will the DD bonus.

As far as the attack speed example, I think that one's odd for a reason. The game actually needs to track your attack cooldown, not your attack "rate" (attacks per second). A 30% bonus, however, does not affect your attack cooldown by 30%, it affects your attack rate by 30%. It affects your attack cooldown by 1/1.3. This isn't a complete thought, but it seems plausible that the fact that attack speed changes can't be implemented just by adding or subtracting a number means they behave differently from other things.

I'm not sure if melee dmg modifiers follow the same principle, but according to several forums I frequent and personal testing priest/lock talents at least are multiplicative. Also I believe power infusion is as well. From my own number crunching the sole exception to this was Darkness, which for reasons passing understanding is additive.
