Same reason it shoudn't be team CRDL.

If we don't know them, then the reason might be they just wasn't good enough. We need a team that seems good in our eye to have the impact I want. And since they cannot kill off members of RWBY and JNPR at the moment the only other team that would fit the bill would be SSSN where Scarlet and Sage could die.

Only they are not on a mission right now.
