You just added weight to my claim that 5e is built saying that certain playstyles are badwrongfun. Adding to that is the fact that players tend to outnumber gm's by a significant degree with most tables having around 4-6 players (give or take) per 1 gm. any survey is going to be largely people who mostly or only play and as a result will not consider things from a gm's perspective of why a wraith or something should blast through 30+ ac like wet tissue paper instead of harmlessly bouncing off like every other melee ranged & spell attack.
Simply saying add them back in ignores the fact that we aren't having this discussion because there was a second or variant version of things like the wraith, ghast/ghoul, trog, rustmonster, various scary oozes, etc that lose their scary bits or have their scary bit nullified if they are up against someone with a magic weapon/armor. We are having this discussion because not only were they replaced with defanged declawed versions but even dmg 280/281 also completely omits those kinds of scary effects. simply putting them back in fights against too many changes in the system & you quickly run into a snowballing slippery slope where you have so many house rules upon house rules that you are playing a different game.
So you want a game that will support your personal preferences instead of the feedback they got from one of the most comprehensive play tests ever done for a TTRPG. Because you know better than the thousands of people that responded to their surveys.
Good luck with that. Personally I'd like a pony that leaves behind gold bars as droppings.
No game is perfect. Personally I only need a handful of house rules to make the game my own and I'd be perfectly happy to play the game without a single house rule.
