Aight I see aim not getting through to you. Let's try though.
No, lowering damage and slowing attacks is not all I proposed nor would that fix the issue. Complexity in move-set must also be decreased. Also in the game world enemy placement and quantity must be adjusted to lower dificulty. Otherwise it'll be, mostly, just as hard
No, properly slowing attacks is not easy to do. You are not programmer or an animator. No, AI can't magic this up for you either a month ago I saw an app hobbled together with AI that had three whole stacks in it with three seperate apps because somebody tried to add a new view with statistics on it with AI tooling.
Once more, for accessibility, should we have low to no horror settings in horror games? Low to no puzzle options in puzzle games? Etc.
You call these people lazy but don't have any clue what they actually do. No. It's not lazyness. They could make shitty difficulty settings that don't fix peoples problems or they could spend many hours doing it right.
Edit: To respond to their edit, I think the just add a difficulty slider argument fundamentally doesn't understand why people play these types of games
