I am not sure high soak is a concern when we are talking of Force and Destiny.
Jedi are really bad asses, I have never seen a Jedi falling because of blaster fire. This is a game where we expect lightsaber fights and duels and a lightsaber has breach 1. For these nice duels to happen the guys will really need high soak values, otherwise one hit and the duel is done.
In brief, it makes sense thematically that Jedi have huge soaks, this or huge defence values. In my opinion high soak makes the game faster (less dice rolling).
I think the rules for Cortosis Armor mitigate the need for high soak. In order to resist the Breach 1, you would need a Soak of 10+, that seems pretty absurd. Cortosis armor takes care of the Breach 1 problem easily enough.
So does a phalanx of unarmed minions.........whatever is the poor, poor Jedi to do when he/she has to cut down a wall of my unarmed followers in cold blood to get to me??...............muahahahahahahaha!!
