Look at Warcraft; in the third part, the Orcs evolved from Barbarian destroyers into spiritual beings, and the experiment was a success. It can be taken as an exemplary standard of how to break stereotypes. But time passed, and Blizzard themselves decided to return to the classics, hence the departure of the wise shaman Thrall from the position of Warchief and the transfer of power to the crude Barbarian Garrosh. Many people don't like this, and neither do I, but if you think about it, it's actually correct. People (I'm not talking about the race, but about us – gamers, readers, role-players) in their desire to be "good drow" and other rejected, misunderstood beauties and beaver protectors, completely forget the role-playing aspect, forgetting that Drizzt and Thrall are exceptions to the rule, not the rule. Salvatore constantly emphasizes this in his books, and Blizzard, apparently, decided to point this out in a more forceful way. After all, if we have smart, good Orcs fighting smart, good Humans, then what's the point of them fighting? They should make peace and live happily ever after. Therefore, the sides must be different; it doesn't have to be a banal good versus evil; let there be order and discipline against chaos and destruction, but there must be differences.
The current Horde of Durotar has actually returned to the culture that the Orcs had before they were corrupted by demons. The Dark Horde and the remaining fel Orcs of Outland are the Orcs who still lead their former destructive lifestyle. Under Garrosh, the New Horde, of course, finally quarreled with the Alliance and began to wage war with them again, but the Orcs did not become what they were in the first and second parts. And many do not support Garrosh.
