How many kindergartners do you think each player could take?
I'll start with 100 Thieves' roster:
Asuna - No shame, would pummel like 15 of them at the same time
Steel - Could not bring himself to hurt a child as he is a father figure to Vanity
Ethan - 5-10, probably could take an average amount
Nitr0 - 0 or else dad buff would deactivate
Hiko - Has to remain child friendly and would; therefore, not be able to beat a kindergartner. If he wasn't child friendly, this guy would be a tank
