I don't think this really be necessary. Judging by how frequently these questions are being asked, some dating back to late last year, I can't see this being a thing. Sure we may get a "what is a good check to insert threat here?" but do you really see people asking about good checks for a Pokemon like Spinda ;)
The moveset pages on this website are a massive fail as would be the pages you are requesting be made. The thing is that Pokemon move tiers, get access to new moves ect and for that reason the counters are always changing. However the most voted counter will usually be the oldest answer based off the usefulness of it at the time + bias voting towards user. In a years time, the page for a counter to Heatran could be completely different. Just look at some of the older moveset questions filled with gimmicks and sets that wouldn't take you anywhere in the current meta game. If only one or two people were allowed to answer a question and them answers were updated every so often similar to how Smogon works, then I would approve. Until then I see it as a waste of time. Do think about how long it takes to ask all these questions.
