Instead of making a new topic to ask a simple question, since it's similar to what's asked here:
Can you point me to a wiki or article explaining why 20% elemental damage is better than (up to) 1000% increased damage for having (up to) 1000 more main stat?
I guess this is because of Multiplicative versus Additive damage multiplier, however I'd like to read something that goes into detail on this please. For reference, I have an item similar to the OPs and I want to know if it is better to have 10,000 main stat (thus 10,000% increased damage) or 9,000 main stat and 20% elemental damage. Does the 20% elemental equal (in simplistic terms) 20% of 9,000 (1,800%) damage increase for that element?
Perhaps a little late but it is simple math: 9000 -> 10000 is a 1000/9000 increase (roughly 11%). And it will be getting less with increasing intelligence due to paragon etc. elemental damage is a separate multiplier (mainstat too). So assuming you have only 20% elemental damage on your bracers you go from +20% to +40%. This means an increase of 20/120 and this is roughly an 17% increase. But when you have more elemental damage on your gear, this can change: theoretically you can have with the element fire way more elemental damage (LON builds): cindercoat, Mage fist, andariels visage, stone of Jordan, lidless wall and the devastator. In this case you go from +140 to +160 so it is a gain of 20/240 and this is roughly 8%
