Forgive me, O All-Knowing One about what Heroes should be, but:
1) Did I say something about the Elves?
2) Yes, the Imperials enslaved the Orcs, but the Mages didn't, and the Beastmen were also very happy serving the Mages, so happy that they rebelled, right.
3) The original table, especially the Dwarves-Orcs, who don't really interact with each other. And the fact that Humans actively fought with Orcs and Necromancers, and Demons fought with everyone - that's nothing, right.
