It’s just us kittens left, and the rain is coming
I know Arctic has talked about this briefly, he probably has some input.I have questions this doesn't address.
What the purpose of suspecting and banning? Is it to prevent over powered pokemon, with few checks and counters, being thrown onto seeming every other team, which make the meta game stale, unoriginal, and un-fun?
If so should we consider banning certain 3 pokemon cores for the same reason? If not why?
Before you pick the easy, small minded answer and say there are checks to every core, the same goes to the pokemon we ban. (ever heard of an ice move?)(btw, on a side note keldeo+skymin is ban worthy but not skymin on its own, imo)
It has never been done by another meta and the only meta that would make since to try is doubles for obvious reasons.
Hypothetically if the core of Lando-T, Thundy, and mega-Kang got suspected and banned. (I believe this core is the most overpowering)
Ignoring you reasons for wanting to try or not wanting to try this idea; would the effect be bad to our meta or beneficial? And why? And does your answer conflict with suspecting individual pokemon?
Imo banning some 3 (even 2) pokemon cores would in the short run see a lot of new teams being built and in the long run a healthier meta where you would see a lot less match ups where 5 of 6 pokemon are the same.
Additionally in the short run our community would become more active with suspecting. And we might even gain more active players from doing that suspecting .
As for the idea itself, I think it's bad. I don't want to be into teambuilding and think "oh I can't put this mon here because it's not compatible with x y and z" kind of like making a set with a pokemon then realizing that the nature doesn't correspond with the moves which is one of the most dissapointing things. Sure some cores are popular but that doesn't make them banworthy either. In addition, "selectively" banning, for lack of a better word, specific interactions sounds unadapative to the meta (it's possible to adapt to every core. See diancie vs chalk, M-Aero's brief rise back when Skymin/Keldeo/Talon was popular, thundurus for jirachi/mence, various sun checks ie talonburd). Part of having a central meta necessitates creativity and innovation by itself. By outright banning a core, inevitably it seems to me more along the lines of "I don't like playing/preparing for this core" rather than "this specific interaction is overreaching in the current metagame", the latter of which I don't believe applies to any cores at the moment.
