So finally what's the goal of all this ...?
Sometimes less miss and sometimes more damages ?
Your suggestion would be boring as hell and in the end you would often deal less damages...
I noticed you changed your post, so to reply to this one also. Regarding first sentence:
ALWAYS less miss, and SAME average or maximal damages.
Damage should be same both on average and in potential maximal value ( eg 24 in in crit case with max 12 roll for example ). You would have exactly same amount of big crits. What would change would be no misses/low hits and also no big no-crit hits ( so no 1dmg or 11dmg for example ). So "sometimes more damage" is true along with unsaid "sometimes less damage" - not to mention that you could say even for current situation that you sometimes have more or less damage .
Regarding second part of second sentence, saying "you would often deal less damages" ignores that you would often deal more damage, so it is incorrect statement since in THE END you would deal same total damage on average.
As for first part where you state that "Your suggestion would be boring as hell" - I guess that is subjective, and mildly insulting. Not only to me, but also to Larian and DoS games, that have exactly same "low miss chances, low damage variability" - so you state that games like those are "boring as hell" and I guess that is your DnD background. But again, majority of potential gamers are NOT DnD veterans.
