Yeah i was trying to do the same on my last playthrough - as i did not like those changes to the rules - forcing myself to use rules like the ones you mentioned and i agree a game mode which would do these automatically instead of us would be amazing, the game becomes clearly more tactical, tense and rewarding (to me at least).
I saw some of the comments saying "then dont use it" and i really tried to play the whole EA like that but that did not really work for me on long term, one reason is that i dont like to keep notice of changed rules in my head when im playing a videogame i want and expect the GAME to set complex challenges for me. Also the game keeps showing me signs for opposite intentions (as you mentioned enemies are still cheating with those actions) and overall its just not the same rewarding feeling at the end of the battles, as i just know im not beating a game ultimately, but some rules in my head.
Also i saw comments saying "use mods then". Im not against mods but they can be tricky with multiple versions and game updates, also sometimes mods i need are clashing with each other etc. so i use them only after a couple of vanilla playthroughs only (like i did for DOS2).
So fingers crossed, im up for a more challenging game mode which includes changes like the mentioned ones.
