Regardless of whether banshees one shot orks, they can still strong attack faster than any ork can get a fast attack off so inevitably they win any and all duels.

I've noticed playing as Orks that their swing distance seems incredibly short for them being so big and having such long arms. It's like they're deliberately pulling their blows. Even considering the strangely tiny choppas they use, they should have far more reach than they do.

As an Ork who was continually punching banshees to death 1v1 using my fist, I don't think that's as true as you'd like to believe. It's when you get swarmed by 3 of them that things change.

As long as you counter (properly) before I get clanged to death, I tend to do alright vs Banshees.

Maybe it's the lack of melee range then?

I'm assume you are using the shoota boy? I've found the melee for that class in particular awful but maybe it works against banshees better?

I was talking before about slugga boys that I find can't compete with the speed of banshees. It could be latency issues also I suppose.

I tied with a banshee once using the Dead shiny choppa vs his power sword. Both broke at same time. Don't think that was supposed to happen but we were clanging power attacks as well. So maybe the different types of attacks also play into durability when clang. Like fast attack clangs give one group a +1 to durability while Power attack clangs give a -1 on the durability comparison.

also it was the dead shiny choppa so that's our "master craft" equivalent maybe that also did something like add a next level tier to the weapon for clangs.

Melee weapon attachments are now a thing, a chainsword if upgraded can now tie with a powersword or even beat it now

I had no attachments on it. Just the dead shiny variant equipped.

I know but it may have a passive or just class as a power sword now since you said it's master crafted

that's why I brought it up. I honestly don't know what goes into making a weapon master crafted.

No way to know but I had a similar situation happen this evening. Chainsword was willing to spam right along, assumed I 'd win because you know, powersword, but that didn't happen we broke at the same time and both got staggered. So barring some kinda upgrade, powersword doesn't count as a tier 2 weapon. I haven't seen an upgrade that increases impact (clang value) I've seen damage upgrades, durability regen upgrades, and charge regen upgrades.
