Dual sword and single sword whirlwind in diablo 2 classic (non lod) do the same hits or having two weapons duplicates hits?

I tryed with two single hand swords and later with one of them (one hand, not dual hand), and I feel the hits and the killing speed is exactly the same.

Any help with this please?

classic ww is always max speed, you either play 2h or 1h + shield
no need for fast weapons or ias on gear

but if you carry two one hand weapon with 100 dmg each, you do twice damage than if you carry one single weapon with 100 damage and a shield? or the same damage?

The weapons alternate, you dont attack twice as much.d

so what's the benefit of using two weapons with whirlwind?

In classic there is non as far as i know - perhaps just for style.

oh, then you mean than in LOD it's different?

do AR affects classic whirlwind? the more AR the more hits you do?

Yes.

Yes it’s different from LoD as many other things
