A) By your own admission, both weapons do 165 points of damage in the 20 rounds. As you also point out, one of them did it by having extra damage and the other by hitting an extra time.
So where was the trade Frank? Any DAMAGE that was supposedly lost by taking accuracy was made up by having accuracy. The end result of two identical characters fighting with these weapons was the same. Thats what I am getting at, its a false trade.
souran, as people have explained to you repeatedly, the trade comes from the fact that the weapon that does more damage
sometimes drops people in one hit while the weapon that had more accuracy
never drops someone in one hit.
It's a gamble. You can either take no attacks or take attack on top of what you're already going to get. When does this come into play? Well, if you're fighting some bruiser monster like a ghoul or a closet troll where you can't take
any hits then the high-damage weapon is your best bet, because the high accuracy weapon won't pull you through even if all of the hits land. Your chances of succeeding with the high-damage weapon are low, but
you still have a chance of pulling through.
Similarly, if you are fighting hordes of enemies, if the high-damage weapon takes less hits to kill enemies then you want that. If the high-damage weapon randomly lets you take out enemies faster, which means that you suffer less hits.
Here's a scenario for you. Fighter A uses a greataxe, a low-accuracy/high-damage weapon. Fighter B uses a rapier, a high-accuracy/low-damage weapon. They all fight goblins, which have 8 hit points.
Fighter A does 10 damage with his greataxe, which is enough to drop a goblin. However, every third attack he misses. Fighter B does 7 damage with his rapier, which is not enough damage to drop a goblin. But he never misses.
They each fight 7 goblins. They fight goblins until they're all dead. The fighters go first. Let's look at their DPR:
Fighter A:
Round 1: 10 damage. Total attacks suffered: 6
Round 2: 10 damage. TAS: 11
Round 3: 0 damage. TAS: 16
Round 4: 10 damage. TAS: 24
Round 5: 10 damage. TAS: 27
Round 6: 0 damage. TAS: 30
Round 7: 10 damage. TAS: 32
round 8: 10 damage. TAS: 33
Round 9: 0 damage. TAS: 34
Round 10: 10 damage. TAS: 34
Average DPR: 7
Fighter B
Round 1: 7 damage. Total Attacks Suffered: 7 (7 goblins remaining)
Round 2: 7 damage. TAS: 13 (6 goblins remaining)
Round 3: 7 damage. TAS: 19 (6)
Round 4: 7 damage. TAS: 24 (5 goblins remaining)
Round 5: 7 damage. TAS: 29 (5)
Round 6: 7 damage. TAS: 33 (4 goblins remaining)
Round 7: 7 damage. TAS: 37 (4)
Round 8: 7 damage. TAS: 40 (3 goblins remaining)
Round 9: 7 damage. TAS: 43 (3)
Round 10: 7 damage. TAS: 45 (2 goblins remaining)
Average DPR: 7
Do you get that? Even though both weapons do the same amount of damage over time, the Greataxe fighter suffered fewer hits.
It's also not hard to construct a scenario where the Rapier fighter was superior. Just give the goblins 7 or fewer hit points, and THEY will suffer fewer attacks.
Souran, if after all that bullshit you can't see the utility of a trade like this then I think you're going to deserve that +ignore.
