Honestly I don't think any of this would result in dramatically longer turns, it'd be way less time than the time we currently lose due to the AI thinking time bug/issue.
But rolling dice is the backbone of fun in D&D. Not seeing them outside of checks is criminal, I think. I want that cool feeling when my friend maxes out his damage dice on a key hit! And once you see the hit dice and stuff, you progress to naturally being presented an opportunity to do your complex reactions. Win win!
I can tell you that having everyone on the table jumping when our paladin did 2 crits in a row with smite for 100+damage after misty step with a successfull save o inside a forcecage against the #thingyouhavetodestroy in ToA for a 1 turn kill felt amazing.
