I agree with caveats. Maybe it's rose-tinted, and obviously makes no direct mechanical difference, but beating an AC vs. percentage to hit has always felt better to me.
Beyond making it simpler, percentages also make gameplay faster and target selection a breeze. Combine that with the fact that you can see enemy HP and a slew of tactics that DnD players would dream to have become possible. It essentially creates a new system, but when combat plays out in 5 minutes vs. 30 min of rolling, describing and laughing, these are necessary changes.
I honestly don't think there's a way to implement it without taking more than it gives. give a "?" for HP, remove the percentages and roll a dice above the selected enemies head with the roll, on success or failure given as the blue/red for other passive checks and saves. Maybe this could be in a future DM mode for people running their own campaigns? Very unlikely I reckon, since you're just taking away information without giving anything back.
