Pathfinder did more damage to the hobby than any other game. There's nothing wrong with a monster campaign, but monsters are monsters. Having a Githyanki in the party is bad enough. Tieflings being so common nobody bats an eye is bad enough. Drow being completely ignored is bad enough. Half-elves and half-orcs being completely uncontroversial is bad enough. Players have gotten so used to these types of creatures as characters that there's an assumption that the narrative setting of the game world shouldn't care either, and it's one of the biggest problems that exists in D&D to me. I don't have a problem with any of these creatures as a player race, as long as they can't stroll into a town without being lynched. They're fucking monsters.
