How should we treat questions specifically related to champions usage in competitive play?
To me, these types of questions seem much more localized and speculative (from my knowledge of the game) than general questions about champ viability. As soon as the meta changes or the top players change, these answers will change dramatically where the general questions about champ viability will not.

Why is Tryndamere not seen in competitive play?
Why is Kassadin not played in tournaments?
