The situation is the following: there are often questions where the querant is facing a very specific instance of a more general issue. For example:
Someone wants to know when a colossal creature would be affected by Symbol. Here the general question is how much of a large or larger creature must overlap with a spells area of effect for the creature to be affected.
Someone wants to know if polymporph cancels bladesong (or rage, or starry form). Here the general question is if polymorph removes only class features, or also ongoing effects caused by such class features.
Sometimes, such questions are then used to close additional, similar questions, because they are a "duplicate" (even though they are asking for a different context of the problem). And it may be more difficult for the querant to accept that their question is a duplicate, given that the other question is talking specifically about another situation.
In all these cases, one could create a general form of the question, and answer the underlying issue cleanly and neutrally, which would also make it easier to refer to it when additional instances of the problem are asked.
This general form would to a large extent have the same logic in its answers as some of the individual questions, but would that make the question itself a duplicate? That is, is it correct to close a question as a duplicate, only because it has the same answer as another question, even though the scope of the question is different?
