Maybe because his Unova team is not so developed? catching 10 pokemon and then getting barely trained was kinda a mistake now looking back, that's where the writers failed, his team needed development.
It's clear his team was all over the place. As much as top 8 for Ash disspointed me BIG TIME, I think he deserves that spot. (and wow people need to stop being so over dramatic lol)
Cameron's team >>>>>>>>>>>>> Ash's Unova team
Chapter N Ash or Gen VI Ash needs to be "redone", a smaller, a la Hoenn team, Ash needs for Gen VI IMO so the mons gets more focus overall ***crossing fingers for the writers***
