So why are you CAPSLOCK SCREAMING as if your house rule is fact?
Also, the issue with 'always evil' violence magnets has been around long before WoW existed.
Also also, people didn't 'invent' the idea of orcs as people to cause a problem, it's been an ethical dilemma as long as the game existed because a lot of people just naturally reject the idea of a stock race as an enemy and inherently evil as a description for races. It's always been an issue, it's just that society has progressed enough that people are comfortable voicing it.
