Is +flat damage and % Enchanced Damage bugged?

[konfeta]

Sample AH item:

Rune Sword with final listed damage of: 571-1131
Affix: +276-651 Damage
49% enchanced damage

571/1.49 - 276 = 107 damage (Rune Sword min damage)
1131/1.49 - 651 = 108 damage (NOT Rune Sword max damage)

So, it looks like the game determines max damage by adding the bonus damage to the min damage and ignoring the base max damage on the weapon. But hold on, it gets better!

Rune Sword with final listed damage of: 409-974
Affix: +258-621 Arcane Damage
44% enchanced damage

(409 - 258)/1.44 = 104 damage (Rune Sword min damage)
(974 - 621)/1.44 = 245 damage (Rune Sword max damage)

The game seems to calculate flat elemental bonus damage correctly (max to max), but, +ED% does NOT work with it.

So, um, wtf? What is supposed to be the correct mechanic?

An even better question - say you have a +elemental damage weapon. How exactly does the orb + max damage add to it? Is the min damage bug going to interfere? Is the +ED% going to benefit the +orb damage?


****
Did some more testing, results:

+flat damage on slots outside your weapon are just added on your final listed weapon damage range (the one right under the DPS), all you have to do to recalculate to account for the bonuses is to add the min damage to the min, max to the max, average the two values and multiply by the weapon's attack speed.

This calculation is not affected by the above shenanigans in the slightest (I've tried weapon with +phys, +phys/ED%, +elemental, +elemental/ED% - all work identically), so it is thankfully very easy to test.

So, I believe that the above bug only affects the item generation. The listed weapon damage and DPS is accurate (at least in relation to the DPS on the character screen).

Isn't this how it was in D2 ? Enhanced damage was on the base weapon damage, and any flat damage modifiers were added on top of that, regardless of Enhanced damage.

G.R.D. (Unless I missed a point)

Yesterday I started researching similar thing.
For me only the + damage(physical) seem to be bugged. All elemental damage bonus on weapon seems to work fine.
I have 2 weapons with bonus physical damage and they both have wrong max damage. The min damage is fine.
Perhaps the formula for calculating the max damage is not base max damage + bonus max damage Or Maybe the devs did some mistake and coded it wrong.
Sad thing is that my weapon would have 100 more dps if the damage was calculated as it is supposed.
Other possibility is that the only the displayed bonus damage is bug and it is not as it is displayed.

Read the post right before yours; it explains it.

Grayson he got a point if I work out the damage range on that weapon by removing the bonus damage (450-709 take away 264-522) gives the base item does 450-264= 186 min and 709-522= 187 max damage and there is no mace that does those damage values, so something broken.
Hmm maybe it just the minimum of the bonus damage? 709 - 264 = 445 nope that don't work as it gives a max base damage of 445 and maces only go up to 356 max damage.

Hmm is it the average damage (264+522)/2=393 and 709-393=316 looks better but according to blizzard site no mace can have that value as its max damage the ilvl 62 mace caps at 306 max damage and the ilvl 63 mace has at the low end 344 max damage this is between the 2 so that not it.

So no matter what the damage values on items are broken for max damage.

+(Physical) Damage takes (Weapon Min Damage + Affix Min Damage) - (Weapon Min Damage (+1) + Affix Max Damage) as its damage range every time. Besides obvious calculations you can easily see that this is true for every item in the AH. How? Just search for magic items (max. 2 affixes) and then for items with a socket (doesn't matter what you choose here) and >200 minimum weapon damage and then >200 minimum elemental damage. You'll notice that all elements (minus cold) go up to ~850-900 DPS while physical only goes up to ~790 DPS.
