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.
That is a fair reason to make such a suggestion, but when the person your advising is actively playing D&D it is still not very helpful.
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.
That is a bit of an exaggeration, but you are correct...I am a god
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.
I've personally have not tried this so I have no suggestions. But in the spirit of the OP, the idea would be to look at how other games do it and see if it can be grafted on to D&D. Maybe it can, but maybe it cannot.
Same goes with trying to do low magic.
This baffles me though. We run a low magic D&D campaign (lvl 15 now) and it is incredible easy for us (that less than 1 page of house rules thing - some which really have nothing to do with low magic). I think 5e is, out of the box, the easiest version of D&D to play low magic. It is baked into the system even. Heck, it would be easy to run a no magic campaign in 5e.
My only guess is that we have different ideas of what "low magic" means. To me it means a setting where magic and magic items are very, very rare. Any chance you would clarify what it means to you?
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.
OK, I didn't see you explained a bit. I personally don't equate classes = D&D. I mean if you get rid of all magic using classes (depending on what you mean by magic using) you still have plenty of classes to play, and you can always go to 3PP for more. If you want a low-magic campaign it seems reasonable to:
- Don't use magic classes - because, well "low magic," or...
- Use magic classes as is, but understand the PCs are special, or...
- Allow only half or 1/3 caster classes (because low magic), or...
- Allow only the magic initiate feat, or...
- Add 3PP non magic classes, or...
- Some combination of 1-5.
This really is very simple and allows for many variations of low magic. I'm guessing you have thought of these so why don't they work for you?
You are flat out wrong about needing to get rid of 3/4 of the monsters. Even if you did that would still leave you with something like 150+ official monsters. But the simplest thing would be to simply ignore immunity to non magic weapons (which is really very few monsters) if you want. Resistance to not an issue.
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.
No one is berating them for not being able to do something. The issue is telling someone else they can't do it because you couldn't. Everyone is different.
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."
That is not what the OP is about. The OP is specifically about not suggesting to play another game when someone is asking advice to play D&D, which they are already doing.
Just because a modified D&D didn't work for you doesn't mean it will not work for others. We all have different expectations.
And you wonder why you are getting push back?
