nu-gorgrond is a literal junkyard. The air is permanently orange with toxic waste. No plants have survived.
The first orc you meet in nu-draenor is a laughing skull orc that sneaks up behind you. If you talk to them they say “no, I wouldn’t know anything about flaying people alive I do know how to flay people, and I can give you a demonstration.”
The second one you meet is called an “impaler” and he tells you he wants to slit the throats of the race-traitors.
The other orcs all say the same master race bs that they will kill anyone who challenges their great leader or their traditions. yawn.
you are threatened at the point of a weapon by genderbent thrall to “pay homage” to the orc clan banners. hellscream shows up and says genderbent thrall is a hothead, and WHAT CALMS HER DOWN IS KILLING OGRES; just so happens the ogres at the ogre internment camp are staging a slave uprising. you are then tasked with killing the uppity ogres to put them back in their place. In the quest text you are informed that the orcs regularly have to put these ogres back in their place every few years by killing the revolters.
In the process of killing the ogre king leading the uprising, you kill a lightbound ambassador. A small regiment THEN gets called.
When you wipe out the small regiment THEN the entire draenei army comes.
I can really tell you didn’t actually play the scenario.
