Some hope comes from Sven mentioning loaded die. If they implement it, they could not only apply it to dialogs, but also to d20 rolls during combat and casual players would be very happy to see 50% attacks hit 80-90% of the time.
I can see Sven's loaded die rules working fairly well: 1d20 for disadvantage, 2d20 for normal, 3d20 for advantage and 5d20 for Elven Accuracy.

“We opted to just go pure RNG for the initial release in early access just to see what was going to happen,” he explains. “We see the people that have really bad luck, and they are really, really angry over it. So, we're going to help them. We're going to add modes to the game that are going to go with things like a loaded die, and that's going to be a bit more manageable. We'll still keep the option of having full RNG in there. We'll experiment with that throughout early access, and see what we should make the default option. That's one of the things that will be driven by the analytics.”
