We've made a good start today I think, but we've barely scratched the surface. A lot more combined experience is needed to confirm our suspicions, not to mention the huge number of pokemon that haven't been started on (Including Bisharp, Mr Cookie)! I'd be very interested in what the community has learned so far.
Just try to keep it concise. I've been editing for brevity (creating this on the fly naturally left unneeded words), because if everyone chimes in with similar points it's gonna get bloated. I also started making save points. When you've finished, make sure to save so that we can restore to old drafts if need be.
As of right now, the pokes with votes for S are Porygon2, Dragonite, Throh, Chandelure, Cryogonal, and Keldeo. If anything on that list (or not
on that list) seems wrong to you, then go vote on it!
