A question I ask earlier today was put on hold, and will later be closed, for being primarily opinion-based (and probably too broad, upon reflection). One way that was suggested of narrowing it, while still solving my problem was to pose a new question along the lines of "What heroes work well with Hero A?".
While it would help me out, and as far as I can tell, it would be a good question, it would also potentially open the door for 20 more questions for Hero B, Hero C, etc. So my question is, is this something allowed here and if so, should it be?
