But the point is and has always been, most of this stuff can be added to 5e, so telling someone to play something else when they ask about adding elements to their D&D game is not good advice. It’s only good advice when someone is asking how to do the thing without any reference to a preferred game, or directly asks for a game recommendation.
Or, someone has tried doing X in D&D, it failed miserably, and so when you ask how you do X in D&D, they tell you to try a different game so as to learn from their mistakes.
Now, apparently, according to you, you are a god of gaming who can make D&D dance on the head of a pin with no problems and, according to some, with only a single page of rules changes. Bully for you guys. Me? I'm just a mere mortal and when I've tried to do these things in D&D, they have failed miserably. Company scale combat - such as what you see on ships - does not work in 5e, FOR ME. It's slow, ponderous, confusing, far too complicated where it needs to be simple and nowhere near granular enough when it needs to be. Same goes with trying to do low magic.
Apparently, for you folks, it works perfectly and that's fantastic. Congratulations. Well done you. Here's your cookie. But, again, IN MY EXPERIENCE, these things don't work worth a damn in 5e. The 5e ruleset is a terrible ruleset for games like this. For low magic, you have to remove 3/4 of the classes, and about 3/4 of the monsters as well. Which means, that, well, I might as well play another game, because what I've got left sure isn't D&D 5e anymore.
So, getting upset at people for suggesting that you use a different system, when those people have TRIED AND FAILED to do what you are trying to do with 5e and then turning around and berating them for not being able to make 5e do these things is not exactly helping your argument. It comes off as incredibly elitist and close minded. "Oh, you can do anything with 5e! You must never, EVER tell me not to use 5e to do something because 5e can do EVERYTHING and do it BETTER than ANY OTHER SYSTEM."
And you wonder why you are getting push back?
