I think the Empire has a few crew cards that trump Kanan. I personally would take Fleet Officer over Kanan any day. Two focus tokens for the cost of stress. Not Focus actions either... so you can even assign focus tokens to stressed ships or ships that already have a focus token!
The Emperor causes dice luck to be more forgiving once every round. He is a huge game changer.
And I haven't even mentioned other greats like Darth Vader, Rebel Captive, and Mara Jade yet. I'm also VERY excited about Agent Callus! For 2 points he is going to wreck some poor ship on the other side. I think we're going to find him in Phantoms... A LOT!
So... I don't see the sky falling anytime soon over some half trained Padawan. Kanan does not know the true power of the Dark Side!
