Sorry I forgot to address your second question, it does hurt it, the split happens further. You can still use it but you have to just adjust.
But to your damage/DPS question Here are ideal op8 versions of each gun
Boss Bekah
D) 662641 (x4 = 2,650,564)
FR) 13.8
R) 3.1
M) 16
Flying Sandhawk
D) 170796 (x8 = 1,366,368)
FR) 2.9 (more while burst)
R) 3.0
M) 38 (13 shots because 3 rounds per shot)
So without a bee on a body shot even with matching elements the bekah does more per shot,
- Bekah 2,650,564
- Sandhawk 2,391,144
Even with Burst fire you can put out pellets faster with a Bekah than with a Sandhawk unless you have a really slow trigger finger, and you get 16 shots a mag vs 13 with the Bekah.
So the Bekah wins on damage, fire rate, and mag size. The sandhawk only wins on Reload Speed by 0.1.
If you add the Bee its a bit different since you get 3 unlisted pellets with the Bekah and 7 with the Sandhawk. An OP8 bee can add up to 1,825,860 so that would be
On Body shots
Bekah 9954004
Sandhawk 16,998,024 without matching elements
So when you add in the Bee the Sandhawk wins, now adding in crits the gap closes but the Sandhawk still wins. Here is why I don’t care. The Bekah still does enough damage but does it with little ammo, the Sandhawk eats though your ammo like crazy and you have to keep swapping to match elements.
If you have run the peak with the sandhawk you know how fast you burn through your ammo, with the Bekah I never have ammo issues at all.
So add in how it has better DPS non Bee, much much better ammo consumption it wins the day for me.
