Is it possible to get numbers for HP bloat and no king of the hill or backstab advantage? Just RAW chance to hit.
Then maybe look into a change in damage with spell save vs goblins to show the nerf.
Afterwards there could be more changes from the 5e RAW simulations for:
The change in Hp bloat and AC and the change in cantrip for firebolt (extra fire over time),
how much longer a PC can survive with the abundance of eating food every BA
How much more damage a goblin does with infinite flaming arrows spells, etc.
Even form this first simulation and graph ,you can already extrapolate the slippery slope Larian went through:
Players complain about missing too much, decrease AC
Enemies died too quick, increase HP
Enemies were being hit but still lasted too long, grant non RAW advantage situations
Mix this in with PC food gobbling, infinite scrolls/spells/bombs/arrows for enemies, ground effects, barrels and can trips. Also realize this feedback only applies to lower level combat, where later on the HP bloat and AC reduction will make spells with saves even more useless than attacking directly against AC.
