Q 4 WW gurus !

hello barbies
i've always played Frenzy, but never WW. want to rectify that, but dual wield or no?
these are my options:

Death Eth cs 2handed 50 ias
ww 5 frames, Berserk 12 frames, ave dam 600+, range adder 2

botd Eth gr. poleax 110 ias
ww 5 frames, Berserk 12 frames, ave dam 600+, range adder 4

dual Grief in pb 50 ias
ww 4 frames, Berserk 9 frames, ave dam 400 each, range adder ???

does dual wielding hit 2x as often? extra range?

i don't play offline so i can't experiment with HE or plugy...

ty!

where are you getting 50 IAS 5 frames Breakpoint with Death?
use https://warren1001.github.io/IAS_Calculator/ for 2.5 version game calc
50 IAS on Death its 42 IAS Breakpoint with 14 FPA, next:
42 14
58 13
83 12
120 11
194 10
Also^everyone counted here are the top 5 bundles of a pair for WW:
5th place - BoTD on CB (one hand) 40'624 dps, / 1.5 crush and blow attack per second (CBA);
4th place - Death + Death (with merc from act 1 with Faith)( Colossus Blade) 91'978 dps with 9 CBA;
3th place - BoTD (main) + Death 75'270 dps 6 CBA (merc 2 act might);
2th place - Grief ( < 34 ias) + Grief - 90'252 dps 3 CBA (merc 2 act might);
1th place - Grief (main 34+ias) + Death 88'134 dps 6 CBA (merc act 2 might can varies from act 1 and act 5 ( Eth Headstriker + Grief fort + Andariels visage)) but for my opinion, Arab from act 2 -onelove forever
Good Luck in the vastness of Sanctuary!
