I feel like I may be answering my own question, but here goes:
Now, for the first time, there will be ways to assign multiple evade tokens to a single ship. For example, Jake Farrell can perform an evade action, and then a ship carrying Jan Ors as a crewmember can change a focus token assigned to it to an evade token. Also, the Lando Calrissian Crew Member card could possibly assign double evades. A focus and an evade can be used on the same roll. Can two evade tokens be spent to cancel two hits from the same attack? I'm assuming not, based on the rule in the FAQ that says effects cannot occur more than once per opportunity. Meaning, one attack creates one opportunity, therefore, one evade token can be spent.
Thoughts?
