Why has Crumbz not been replaced on Renegades?

With the addition of ninja, and the removal of the god awful support thing they had, they're actually looking strong, crumbz just doesn't think at all, i don't know how he stays in challenger, he makes so many bad plays, and occasionally makes one good big one, but the lack of consistency isn't good for the team, could you imagine renegades with say meteos, IWD, or anyone who is more consistent? they would probably be in the top 5 right out of the gate.
