Just ran some numbers, I made my FvS a Drow because of not needing OTWF in the build, planned to TR him to an elf once I had min2s available and could drop improved crit for it. Feats are PA/Toughness (monk bonuses), quicken, imp crit, empower healing, extend, TWF, ITWF, GTWF. Saw that I could keep imp. crit and use lightning2s, wanted to know how damage would compare on "ordinary" enemies (no fort, no DR/anything)

Not asking for opinions or obvious statements about lightning strike weapons vs. pitfiend DR (practically all endgame bosses), just looking for someone to take a glance at my math on these calculations and ensure I did not screw up.

Ancillary information for those who may use these calculations:
Humans lose 3 to hit on both hands relative to the Elf (possibly only 2, see below)
Drow lose 1 to hit on the mainhand relative to the Elf
Human boosts will soon be usable in conjunction with class-based boosts, possibly giving the human a burst damage advantage
My calculated strength for all three is 34 (+12mod), accounting for 18 + 5 levels + 2 rage + 3 exceptional + 6 item, BUT if I add in a +3 tome the human comes out 1 point of strength mod better owing to human adaptability evening out the numbers.
Against a DR15/material (i.e. Harry on Normal) the Drow loses a total of 600 damage over the 40 swings I accounted for. This defecit obviously expands as the DR scales.
Lightning strike damage is calculated according to a 2% reported proc rate.
If the loss on hit for not having OTWF didn't matter (as is frequently the case), you could always just use L2s on the Elf or Human.

MAINHAND

Damage mod = 12 (str) + 5 (PA) + 9 (warchanter song) + 3 (divine favor) +5 (weapon) = 34

Miss 1 = 0
Hit 15 = (5.5 base + 2.5 slicing + 7 holy + 3.5 burst + 34 mod = 52.5) x 15 = 787.5
Crit 4 = (5.5 + 34 + 6 seeker x 3 = 136.5) (+ 2.5 + 7 + 3.5 + 11 burst + 11 blast = 171.5) x 4 = 686
686 + 787.5
