I wouldn't mind if they moved things more back in the direction of the standard rules. It doesn't have to be an exact match.

I don't mind things like Firebolt lighting someone standing in oil on fire. I do mind Ray of Frost targeting a person, dealing damage, creating ice on bare ground beneath them, then they immediately go prone.

I would not mind Fighters getting Shove as a bonus action. Shove being a bonus action for every single class is far too strong.
The similar thing with Jump/Disengage. It's too easy to avoid AoO.
