No, I remember asking about the rules for finding secret doors, getting two, MUTUALLY EXCLUSIVE and CONTRADICTORY answers, that apparently aren't a problem at all. You've still not clarified how mutually exclusive answers are not actually contradictory.
I already explained that. But here goes:
One, the official rule is that both skills are used: Perception to find the door, Investigation to figure out how to open it.
Two, because neither I (who said Investigation) nor the other person (who said Perception) really care. We weren't quoting the official rule; we were showing what the section on skills said and how the skill descriptions indicated that the skills we chose could be used to find secret doors. Again, you failed to acknowledge the existence of an actual rule involving finding secret doors. You're quick to "gotcha" people but very slow at admitting when you're wrong.
And the answers we gave
weren't contradictory, just different. It'd be like if the question were "how do you inflict damage" and one of us said "use your action to make an attack roll" and the other person said "use your action to do something that makes the other person have to save or take damage." Two different methods, both perfectly within the rules, not at all contradictory.
Aaand you still didn't answer my question. Actually, you didn't answer
either of my questions. I feel that if our positions were reversed, you'd be quick to point that out, perhaps with a condescending "ROTFLOL you can't even answer a simple question!!1!" as is your wont. And so I shall ask them again. Perhaps this time you'll actually answer them.
1. If you have a party that includes a ranger, and you come across a flood, does the DM say "nope, no matter what you do, you can't cross"? Do you try to come up with other solutions and the DM refuses to allow them to work? If so, why do you think that's a problem with the rules and not with the DM? Have you spoken to the DM about this behavior? Have you considered getting a different DM, since this one seems antagonistic?
2. Why do you claim that
nobody has come up with exploration rules for D&D in 40 years? There are exploration rules in the 5e DMG and in several other books for this edition, there have been exploration rules in every other edition of D&D, there are probably hundreds of websites with information on exploration in D&D or interesting encounters (many of which are non-combat) or things to find while exploring, and lots of 3pp books, such as Level Up, being produced by this very site, and AiME, which I know you know about. Wouldn't it be more logical to say that you simply haven't researched them?
