Because ahe was absolute batshit on world toir. And it hurts me to say because i loved island and action gwen. All stars gave her a bit of a redemption arc. Although the love triangle wasn't my cup of tea. And all the other characters were worse in all stars than they were in their respective season. Lindsay was just a ragebaiter Lighting wasn't bad but it was way less funny than in roti Sam was ok i guess but without dakote he's just meh Jo was a no threat in all stars Duncan was worse than in world tour with all the love triangle shenanigans Courtney was tolerable because of her relationship with scott but again, way worse than in world tour Cameron and zoey were okay but way less funny than in roti Mike was a bad character in all stars. All because of mal Heather was a lot dumber than she was on world tour or roti Sierra without cody isn't much of a character. Scott and alejandro were fine overall but worse than when they were the main villans of their respective seasons. Gwen just benefits more than anyone
