I mean, once your ship has lost its shields and has damage...why would a player ever NOT take the 'free evade' action? It literally costs nothing to do - no opportunity cost or anything at all. There is absolutely no in-game reason not to take the free 'evade'.
And Ysanne Isard eats up 4 points, so it's a safe bet someone bringing her along is doing so because they want free evades, not just to spend points for the heck of it.
Yet, somehow, in the very near future, I can see another match starting a heated argument over whether or not the ship with Isard on it had taken an evade action when the player owning it forgot to put the token down...
