Are you talking about the Warcraft Movie? I ask because it’s not canon to the main Warcraft universe, at all. It’s not even a different time line. It’s an entirely different universe that is thankfully, being put out to pasture to die.
Probably because writers make it up on the spot and don’t really think about it too much.
I swear, someone at Blizzard loved Mandalorians from Star Wars and said “Hey, we should make Orcs like that.” Because lets be honest, before WC3, there was no reference or hint that Orcs were an honorable race, they were just ugly green dudes.
The Elementals are all hanging in their Elemental House. Talking about the intricate flexible rule system of orcish dueling rites. And if they constitute helping orc shaman.
Thrall is extremely conflicted because he killed his best friend’s son, who happened to be someone he is at least partially responsible for putting them in that position.
He did not cheat at all, but that weighs down on him heavily, and the inner turmoil is why the doomhammer doesn’t work as well for him anymore.
The elements don’t care, he can still do the element thing really well, but the Doomhammer has a history with causes and such. Thrall didn’t believe in his cause anymore due that whole “Killed my adopted nephew” thing, so the doomhammer became worthless.
Debates like this are why I wish more time was given to these moments to flesh them out, so that the people who actually read don’t have to explain this to people who just make things up.
