My Fuma will never fall below 600 damage with no buffs up other than poisons, with my minimum unbuffed Raiton being about 756 (Raiton being unaffected by poisons or DE). If your minimum Raiton is 44 above mine, you should never be seeing 585 Fuma Shurikens. So the base difference is less than the 25% you're saying it is, unless all of your Raiton casts are somehow getting Foe Requiem. There should only be about a 12% difference before accounting for Foe.
Second, in your last paragraph you compare 9 Raiton casts (7,200 damage is 9x800) against 8 Fuma casts (8x600 is 4,800). Correcting for this, it should be 6,400 vs 4,800. 4,800 is 75% of 6,400, which is the same (exaggerated) 25% you got in the first paragraph. Which makes sense, because the % change isn't going to change as you keep going.
Now, if you factor in DE, FR, and Venoms, you have about 316.8 Fuma potency vs 396 Raiton potency. That's a .8:1 ratio. So you should lose about 20% of your Ninjutsu dps if you have Foe Requiem up for every Raiton cast. Every cast that you don't have it up for moves it closer to the 12% I mentioned in my first paragraph, and Battle Voice will shift it slightly back towards the 20%.
But we're talking about probably ~17% loss on what's currently, according to your numbers, 30 DPS. So, a 5 DPS loss at current gear levels (maybe 6 or so because I doubt either of us are BIS). Even if our DPS from Ninjutsu quadruples in HW, that'd be about 20-24 DPS lost out of probably over 1k DPS. So, a 2% loss of total DPS? That's not huge.
