It's been mention several times that they've got it all turned upside down with regards to speech checks. We should be getting multiple chances at success, not failure. Also the DC's tend to be a bit too high in my estimation.
I think I can agree here. Success should open up new paths, failure should close doors.
I personally like that there are multiple checks in a row, but they should feel more like a reward if I make them. A few times I felt that I could get a more mediocre but acceptable outcome, where as rolls tended to give me reward or punishment.
I do like the check system though, and I like that failure is an option, this makes the game feel more DnD than any other DnD game I have played.
Maybe either have high risk, high reward, or have the option to "stick with what I got" when presented with more rolls. At the same time, if I was a DM in scenarios where I wanted something to be possible, but very hard, I would do multiple checks too.
