This isn't supported yet in the emulator code, but I am writing scripts for it anyway and have a question about what the actual difference is between "Decreases Damage Per Second" vs "Decrease attack speed"?
Are those attributes two different things? Or by lowering attack speed you are essentially lowering DPS? That's the one bad thing about using a Wiki to build your knowledge... so many people put info in interpreted their own way. I am second guessing this one.
TIA

I can't remember EXACTLY what the DPS mod does. I believe all it does is increase base damage. I know on my ranger, an increase in DPS would increase my auto attacks by close to 1,000 - 2,000 damage but i know DPS does not effect attack speed in any kind of way. And of course, decrease in attack speed obviously just decreases attack speed and nothing else.

There are actually spells that raise and lower the DPS stat. There are also spells that raise/lower the attack speed stat (haste). There are also spells that raise/lower casting speed (spell haste).
They are all different things and mildly confusing

Ok cool. As long as I know there is actually a difference between Attack Speed and DPS - cuz in my brain, I figure a higher attack speed = more DPS
Thanks for the infos.

Dps mod affects how much your weapons auto attack dmg does by a %. It is affected by diminshing returns 200% is cap = 125%
haste is increase to attack speed and it is affected by diminshing returns. 200% is cap and = 125%

- Item-based haste effects no longer stack with each other. You will gain the best haste effect present on any one item. For example, if you wear a belt that provides 15% haste and a bracelet that gives 20%, you will receive 20% total worn haste.
- Haste gained from item procs will not stack with itself or other haste procs. That is, if you have two weapons equipped that both proc haste, the effects will not stack. However, proc haste does stack with worn haste and spell haste.
- Spell haste stacks with both worn haste and proc haste. Haste spells from different lines will stack with each other. For example, Monk self haste stacks with their group haste buff and the haste gained from their offensive stance, since these are all different spell lines. Bard haste stacks with Enchanter haste, but two Bard or Enchanter haste spells from the same line will not stack with each other.
- In summary, haste stacking works as follows: 1 haste item + 1 haste proc + 1 haste spell per line.
since then there have been attackspeed +2 adorments and haste adornments the + 2 attackspeed stacks with everything the weapon adornment haste only stacks with the weapon no other haste item.
