I just gave the autofire option a try. It works OK but not how I'd hoped. It only appears to work with the attack button right now. Instead of pressing attack repeatedly, you can hold it down to have the same effect. The drawback is that you can't do the magic infused attack (which is normally performed by holding the attack button). I was expecting to see an assignment key in the controls UI that would force the magic infused attack. This feels like a relatively trivial change for them to make and is probably the kind of thing they'd hope to reveal in an early access period.
I did see an option in the accessibility menu to auto fire when holding the button, but haven't tried it out. I'm not sure how that'll work with attacks that you can hold to empower. I'll try to give it a whirl tomorrow and report back.
Everything went smoothly with the exception of the limousine. I ordered a party bus and received a 90's Lincoln stretch on its last leg. It was a little embarrassing but we all made the best of it. If I could go back, I'd definitely book with a different company.
