Hunting traps are tier 1 and there are no tables or rules to help DMs adjudicate stronger traps.
You keep saying this. But the play loop and ability checks are there for DMs to handle anything that is not explicitly stated in the books (and, heck, even for things that are explicitly stated in the books as the rules serve the DM and not the other way around).
I’d rather not see 5e turn into an edition where Set Traps, Use Rope, Bend Bars and the like become codified and play sessions require significant rules-lookup time. The community has already been there - and can still be there if they want. It’s just a different game than 5e.
Now, for 5e, I wouldn’t object to seeing another crunch book where some of these things - like trap setting and other exploration type activities - are expanded upon, much like Xanathar’s dealt with Tools and provided suggested DCs for said tools. But even then, those examples were not exhaustive. Baseline 5e expects players to describe actions and the DM to make calls in the moment to keep things moving.
