The principle needs to be how to make the most out of the D&D system rather than start changing how it works. Changing it will lead to a chain reaction which we are already seeing. Lowering AC and increasing HP makes all spells that target DC or HP weaker. Then you need to address that. Then you need to change something else.
In the case of misses, they should just embrace the fact that armor soaks all or nothing in the AC system. Animate those soaks. It would also give better visual feedback WHY you are not doing damage. Which gives you a clue which tactic works best against that enemy.
And I want my tanks to feel like tanks instead of elusive butterflies. I want to hear metal clashing instead of a woosh.
This sums up my feelings about it quite well. I wouldn't object to having smaller battles either (or a larger party for that matter
).
