True, but isn't that the case with most monstrous races? They aren't tremendously common, and (at least in my homegames) it's generally easier to attempt to hide your monstrous features (Disguise Self, etc)
It’s just more so with goblins because well, the grove is currently fighting them. With the current story, it’ll be hard to implement goblin player races.
I tend to avoid monster races in games in general. It’s a burden and once discovered you sometimes force others to play along. Because either your character should have been killed or exiled, which obviously ruins and disrupts the game. Or the DM has to make some contrived story and the others have to accept it so you can continue to play that monster.
Mind you, this is my experience. I’m sure others have other opinions.
