I wonder if Auto-fire is easy to block.
All depends on how FFG decides to implement a blaster deflection mechanic. Saga Edition had it so that a Jedi could deflect an autofire attack, but they still took partial damage if the attack would have otherwise hit (with main perks of autofire in Saga Edition being that it was an area attack and the ability to deal partial damage even on a miss).
My take has the Jedi and the shooter making a contested roll; if the roll is a tie or the Jedi wins, then Auto-fire is neutralized since the shooter failed to land a hit. In the case of the Jedi winning, Auto-fire's not intended to be an option since my talent is just (as intended) just deals damage based on the weapon*. There's no written provision for activating various qualities (or even a critical injury) on the Jedi's part if they win the contested roll, though the intent was "shot is deflected and the shooter eats their own blaster bolt." As it stands, any GM's using said homebrew talent would have to decide if allowing the Jedi to activate things like Auto-fire or other activated qualities (such as Knockdown) is kosher for their table. Seeing as how the talent only exists in one specialization (one that I noted should only be allowed with GM's express permission) and is a 4th Row talent, I don't see it as too horribly overpowering to allow the activated qualities from a shooter's weapon to be triggered if the Jedi had enough Advantage from the contested check to allow it, but I'd draw the line at being able to trigger a critical injury.
I am revisiting this, based on some feedback I got from one GM about how an NPC of his used this talent to lay waste to the party after the Bounty Hunter of the group opened fire with a heavy blaster rifle and having plenty of Advantage with which to trigger the Auto-fire quality. I might outright disallow the Jedi being able to trigger activated qualities on the shooter's weapon, or increase the difficulty for the Jedi by one if the attacker is using Auto-fire. The change is easy enough to conceptualize in my head, but the trick would be getting it through on paper.
*plus each success that the Jedi had over what the shooter got; so if the shooter used a heavy blaster rifle and rolled 3 successes while the Jedi rolled 4 successes on the contested roll, then it'd be the heavy blaster rifle's base damage +1.
