Someone did the math on d2.net
Base damage: D
LM Multiplier: M
+% Lite Dmg: P
-eLR: E
Resistance: R
Total Damage: D(M+P)(1+E-R)
Crescent Moon: D(M+0)(1.35-R)
Facet PB: D(M+.30)(1.30-R)
So, the question becomes:
D(M+.30)(1.30-R) > D(M)(1.35-R)
(M+.30)(1.30-R) > M(1.35-R)
Let's plug in some random LM multipliers:
LM = 4 (400%)
(4.3)(1.30-R) > 4(1.35-R)
5.59 - 4.3R > 5.4 - 4R
.19 > .3R
.633 > R
[highlight]R < .633 (63.3%)[/highlight]
LM = 5 (500%)
5.3(1.30-R) > 5(1.35-R)
6.89 - 5.3R > 6.75 - 5R
.14 > .3R
.466 > R
[highlight]R < .466 (46.6%)[/highlight]
As you can see, the higher you push LM, the less and less useful +%LiteDmg becomes, and the more important -eLR becomes. We can safely assume 400% LM is within reach of the majority of Lite Sorcs, and 500% is within reach of the upper tier.
If the sorceress is using an Infinity merc, in every one of the situations where a faceted PB is better, the monsters in question get pushed down into the negatives (extremely negative), to the point that the weapon difference is negligible. However, as we get to monster with high and higher resistance, the -eLR becomes increasingly effective.
For a pure Lite sorceress (or even a CL/Orb), I wouldn't consider any other weapon than Crescent Moon if I could maintain 117FCR.
