@orckilla: I see your point. For myself, I loved DOS2, and also I really am enjoying the DnD style combat and the dice rolls. In other words, I like the DOS2 system, and I also like the DnD system. They're different. (We can only hope for DOS3 one day....)
@dreambled: Regarding confirmation rolls, I actually enjoyed getting a second roll to open a book. This heightened the tension: I already failed once. I only get one more chance.... Perhaps a "second chance" roll could be something a character to choose, or a consequence of having high wisdom or intelligence, or something. (Forgive me, I'm not familiar with the 5e ruleset.)
That's what advantage/disadvantage is for. But don't make me succeed a check, do a different check, fail that one, then say HA, welp! Nevermind!
