Are the designers "lazy" or is it the DMs who are "lazy" because they can't be bothered to take 3 seconds to make a ruling?
The designers. I already stated that.
Is it really that incomplete? Is a tight, hard-coded game really what most people want from D&D?
Yes. Look at
ALL the sites, tweets, etc. online about people asking for clarifications, arguing about design, or lack of design.
If the game is "tight", and people don't like the rules, they can change it, but at least they have a basis for comparison. When left "up to the DM" willie-nillie, it makes it much harder for players and DMs alike IME, especially newer ones.
Somehow it's always the D&D designers who are lazy, but never the players themselves.
They get paid for it. So, it would be nice if they completed the job.
Which of course is nonsense.
Not at all. Sometimes players are lazy, too. And DMs can be lazy, but creating complete, fun, compelling game design is
not their job.
And to be clear, the deisgners aren't "lazy", the design paradigm they are using is. This is why I call it "lazy" design.
That's just with a quick search...
Basically, this the problem which led to the "incompleteness" of 5E:
With 5th, we assumed that the DM was there to have a good time, put on an engaging performance, and keep the group interested, excited, and happy.
This is fairly unnecessary as this has pretty much always been true about the DM. Sure, some to greater effect than others, but it's been there.
It’s a huge change, because we no longer expect you to turn to the book for an answer. We expect the DM to do that.
"
We expect the DM to do that." Really? LLLAAAA-ZZZZYYYYY!!!!
So, instead of giving me a complete game system, with concrete rules and systems, where players and DMs alike aren't left scratching their heads, they want people to pay them good money for lazy design.
Sure, of course we all know not everything about a game can cover every eventuality, but the issue is where they
have a rule or feature or whatever, and its unclear just how it is supposed to work. We end up with thousands and thousands of threads, posts, tweets, etc. asking for help or guidance because the designers decided they want the DMs to do it.
And it isn't even like many of JC's tweet responses are even helpful. "I have a question about XYZ, did you intent this or that?" Response: "the text is clear." Gee, really...? thanks for nothing.
