I would give Parvati a 0 as sabotage and this is coming from someone who actually likes her.
Actually I wouldn't say I like her. I just definitely don't dislike her. I just know she'd be getting way too many 10s. Her win in Micronesia was LUCKY, by the way.
Is Parvati a good player? Yes. Is she extremely overrated? Yes.
Edit: To clarify, I don't mean that it was lucky as in ''she didn't deserve it at all'' cause I do think she played a great game but I also think a lot of circumstances were just on her side.
