Neither used headbutt.

I've seen so many orcs die because they didn't use it, it isn't true. There was a shaman who used to kill orc after orc outside the village, until one decided to headbutt him at which point the shaman died.

Those two orcs should not have died. For starters, the druid could not have followed them through the village if they just retreated deeper into it. And as I said, they could have headbutted (might have required reduce). Headbutt lands very reliably, even at 75%. It is one of those skills that I'd use three practices on. Most I'd use two.

Both may have used metal weapons.

Neither seemed to make great use of bloody skins.

The log I am talking about, the orc wasn't in any advantage other than surprise meaning he got the first attack. The group of three all seemed pretty healthy, and had that orc used bloody skins he probably could have killed the warrior too.
