If you are using the new Falcon title on Rey, you are probably going to end up with a lot of rounds that you don't get an action while trying to keep your target in arc. Kanan should get around this, but I'd rather spend my action on a single sure thing focus token than taking a gamble with Lando.
If you're using Rey and Finn, I'd be mighty tempted to give that last crew slot to Jyn Erso.
