Disagree here. The difference is so negligible. A GS LS is a d10 (5.5) and a scimitar is d8 (4.5).

Since scimmy > LS in most situations, chances are you would spec for Scimitar.

Now lets compare a few cases, assuming PA, STR, etc. falls under the "base" category (I'll take scimitar damage, and subtract LS damage from it:

No enhc for either/enhc for both, IC, GS:

Code:

0% Fort: [19*(Base+2+4.5)+1*(Base+2+4.5)*6]/20 - [19*(Base+5.5)+1*(Base+5.5)*4]/20 = -0.7 + 2*Base.
25% Fort: [19*(Base+4.5)+1*0.75*(Base+2+4.5)*6]/20 - [19*(Base+5.5)+1*0.75*(Base+5.5)*4]/20 = -0.7625 + 1.5*Base.
50% Fort: [19*(Base+4.5)+1*0.5*(Base+2+4.5)*6]/20 - [19*(Base+5.5)+1*0.5*(Base+5.5)*4]/20 = -0.825 + 1*Base.
75% Fort: [19*(Base+4.5)+1*0.25*(Base+2+4.5)*6]/20 - [19*(Base+5.5)+1*0.25*(Base+5.5)*4]/20 = -0.8875 + 0.5*Base.
100% Fort: [19*(Base+4.5)+1*0*(Base+2+4.5)*6]/20 - [19*(Base+5.5)+1*0*(Base+5.5)*4]/20 = -0.95.

As the results show, for anything except 100% fort, the scimitar is better, since your base, even at lvl 1, will be +4, and that's enough to counter the -0.8875 damage per hit penalty. In 100% fort, less than 1 dmg per swing is almost nothing.

Now, enhc (favouring scimitar):

Code:

0% Fort: [19*(Base+2+4.5)+1*(Base+2+4.5)*6]/20 - [19*(Base+5.5)+1*(Base+5.5)*4]/20 = 1.8 + 2*Base.
25% Fort: [19*(Base+2+4.5)+1*0.75*(Base+2+4.5)*6]/20 - [19*(Base+5.5)+1*0.75*(Base+5.5)*4]/20 = 1.5875 + 1.5*Base.
50% Fort: [19*(Base+2+4.5)+1*0.5*(Base+2+4.5)*6]/20 - [19*(Base+5.5)+1*0.5*(Base+5.5)*4]/20 = 1.375 + 1*Base.
75% Fort: [19*(Base+2+4.5)+1*0.25*(Base+2+4.5)*6]/20 - [19*(Base+5.5)+1*0.25*(Base+5.5)*4]/20 = 1.1625 + 0.5*Base.
100% Fort: [19*(Base+2+4.5)+1*0*(Base+2+4.5)*6]/20 - [19*(Base+5.5)+1*0*(Base+5.5)*4]/20 = 0.95.

As you can see, in

*every* case the scimitar wins. Thus, with scimitar enhc, you're better in every case than using a LS.

Now, enhc (favouring LS)

Code:

0% Fort: [19*(Base+4.5)+1*(Base+2+4.5)*6]/20 - [19*(Base+2+5.5)+1*(Base+2+5.5)*4]/20 = -3 + 2*Base.
25% Fort: [19*(Base+4.5)+1*0.75*(Base+4.5)*6]/20 - [19*(Base+2+5.5)+1*0.75*(Base+2+5.5)*4]/20 = -2.9625 + 1.5*Base.
50% Fort: [19*(Base+4.5)+1*0.5*(Base+4.5)*6]/20 - [19*(Base+2+5.5)+1*0.5*(Base+2+5.5)*4]/20 = -2.925 + 1*Base.
75% Fort: [19*(Base+4.5)+1*0.25*(Base+4.5)*6]/20 - [19*(Base+2+5.5)+1*0.25*(Base+2+5.5)*4]/20 = -2.8875 + 0.5*Base.
100% Fort: [19*(Base+4.5)+1*0*(Base+4.5)*6]/20 - [19*(Base+2+5.5)+1*0*(Base+2+5.5)*4]/20 = -2.85.

Even with LS enhc, a scimitar without them is still better. The most difficult case to beat (75%) requires a +12 modifier to base damage. That's 5 PA, and 24 STR, for MH, and 5 PA 48 STR for OH. Although the OH case might seem like a a lot, every other increase to base damage subtracts 4 from it, so with even a crappy +4 bard song, your STR only needs to be 32. And that's notwithstanding that its the most extreme case.

Thus you can safely conclude that even

*with* LS enhc, a scimitar

*without* beats it against most fortifications.

Against 100%, the difference between scimitar with enhc and LS with enhc is 0.95, or less than 1 dmg per swing - something barely noticeable considering all the other things, and that many 100% fort mobs (liches, skeletons) require bldg to bypass DR.

Thus, scimitars are pretty much undeniably better in almost every way (except against other players, some constructs, zombies, and elementals).
