A pokemon shouldnt be S for simply excelling at a role, because at the end of the day you will be facing 3 different types of teams, and when you decide to place said mon on the team it should be able to flourish in all matchups and not be a liabiiity. The best mons in the tier should not be a liability in most scenarios, hence why they are the best, truly making it very low risk to use in every realistic scenario. The problem with this argument is that something Mega Lopunny should be S for its role in dismantling offense, so yea , its a natural bias for the opposing offensive player to want this in S. But at the same time, the users of mega lopunny who face balance and stall, and the balance and stall players who face mega lopunny will agree that despite PUP and encore, Mega Lopunny is not consistent versus these types of teams, so thats not really what an S rank is even if its close. Those mons you mentioned such as Genesect and Greninja excelled against all types of teams and limited team building across the board . Gene sect just cheesed with u turn and download boosts on either offensive side and was able to clean up every play style. Greninja, had low kick and gunk shot for slower teams and had an amazing speed tier for offense . Clefable can easily sweep all types of teams with CM , sure its not a traditional sweeper but the problem is since most of its switchins are shaky and its not the easiest mon to ko its an easy candidate for S.
Then for the counters argument, sure most S rank mons don't have counters , but you have to consider that at the same time they also have small amounts of counterplay once they have put on their pressure and the most important part is that they carry the team on their back while asking for little support back. Lack of counters =/= lack of counterplay, as otherwise SD megachomp, hydreigon, and even kyurem B would be S. In other words, these mons have flaws just like Hoopa that prevent them from being consistent versus all types of teams. Hoopa is definitely a better wallbreaker than those 3, hence why he is ranked higher and fits in A+, but it also suffers some of the same problems with low speed for an offensive mon which is compounded by the fact it has no resists and bad physical bulk. That NP set you mentioned isn't as common as the scarf and mixed LO sets, and it seems like unless the opposing team is pretty slow you aren't getting off a NP . Hoopa u needs to make the most of its turns and should spend its time nuking before its inevitably forced out the next turn. Sure , Hoopa U is the best stall breaker in the tier and i won't go into detail about the downfall of stall in the meta, but Gothitelle (for which is a controversial topic for another time and place) has a similar problem in that despite being a disgusting stall breaker it is not consistent versus other play styles which is why its only B + .
The descriptions as AM said multiple times are literally dumbed down to just give newer players a simple guide on how effective a mon is in the metagame. So when they look at S ranks, they will see that these are by far the best mons in the game as they hold high amounts of viability. Then when they look at C ranks and see some thing like Cress they will get the basic understanding that that mon has lots flaws limiting its effectiveness. The descriptions aren't by any means something to solely base your arguments off of , and especially for the higher ranks arguments should be supplemented with its effectiveness against the playstyles, how abundant its checks are, its counterplay against those checks, splashability /utility, and preferably high quality replays.
That might be right, I shouldn't have brought in Greninja and Genesect because they were broken, of course. And I also realise that a pokemon has to be effective versus lots of many metagames to be S rank, which is why Lopunny isn't S. But as it stands now Mega Metagross was basically S for its All-out-attacker set, because it preformed said roll immensely effectively. While M-Altaria has basically not one set that makes it S, but it is a great sweeper, but what makes it S is that it has so many good sets which makes it immensely unpredictable. Clefable is what most people think is the best pokemon in OU at the moment, it preforms a support set amazing whilst many of its sets are great and a few are good.
See, the different between Hydreigon, Kyurem-B, Mega Chomp and Hoopa is that all of those pokemon and different sets that break different pokemon, if you run banded Kyurem-B there's a list of counters, but there's also a list of counters to the Mixed set. But the problem with Hoopa is one, most stall mons are specially based or they used fixed damage moves (Chansey, Cresselia, Scalds) So in general its physical bulk is rarely a problem for it versus stall. But Hoopa also only needs to run one set to beat every single mon on stall reliably. Here are some calcs so people actually realise how dumb this pokemons existence is.

^lol
I'm going to go all caps now because I'm honestly tired of this glaring problem in OU that's completely being ignored, sorry in advance AM.
At what point do we stop accounting stall as a viable playstyle anymore? Because in the current metagame you have two pokemon that will 100% of the time, unless you make crazy, irrational doubles eradicate stall. I can see moving a lot of shit up because of stall is basically non existent at this point. Do all of you collectively agree that stall isn't meant to be? Because a lot of us enjoy it... Really, in a perfect world I'd see gothitelle gone and Hoopa gone. Yes, stall isn't existent and that's why Hoopa isn't S but don't you ever realise that the REASON stall isn't existent is because of Hoopa and Gothitelle?
EDIT: I don't want to this to be scoffed off and die out... If you have something to say, please take a little time out to address your opinion.
