In 7.27, many things were changed to stack diminishingly rather than additively. For example "Heal Amplification now stacks diminishingly rather than additively".
Can someone help me do the math on the difference? Let's say there is a Pugna with his 20% heal amp talent, paladins sword 17%, and holy locket 35%.
When it was additive, the percent increase is 20%+17%+35%=72% heal amp increase.
How does the math work when it stacks diminishingly? Is it 1.2 x 1.17 x 1.35=1.9? That doesn't makes sense since it is buffed.
