I think that this would be a great idea. On each Dex Page, there would be 5-6 lines about the Pokemon, it's strength and weaknesses, what it is usually used for, etc.
There could be a Reservation Index, where you can reserve the Pokemon you want to do. Then you have 3-5 days to complete it, and send it to the Quality Team, who check the competitive side of the team (i.e: have they explained about the Pokemon's viability? Did they miss out some important details?). Once is has been verified, it can go to the Grammar team, who check the grammatical side of the evaluation (commas, spelling, etc).
I don't believe it would be hard to manage, and I'm fine with being in charge / supervising this idea! This resource would be helpful for newcomers. Here is how they would look like, except with much more detail!:
Users that continuously contributed to the Evaluation Resource, by writing up summaries, could get recognised for their hard work, by being added to the Quality Team, and users that continuously examine these explanations can be added to the Grammar Team.
I believe that this would be a great idea for the site, as it would benefit a lot of people!
