I don't think weather in general is nearly consistent enough to warrant a suspect in any form. It's not matchup reliant so much as teams are either weak to weather or not. The only reason why there are a sizable number of teams weak to it is because people choose not to prepare for it because of how rare it is. SmashPass is also impossible to prepare for really. Your team had to be able to handle pretty much every offensive Pokemon at +2/+2/+2 or have something for +2/+2/+2 Xatu as well as a phaser or have a Haze user, of which there are zero good users that don't mind using the moveslot on it. With weather, Kangaskhan + something for Kabutops pretty much covers it most of the time. Stall doesn't have much of an issue with it because it can afford to run two dedicated Water resists and a Quagsire (which covers most Kabutops and the occasional Belly Drum Poliwrath as long as they don't flinch). Mega Audino alone does a fair job handling weather barring Growth Victreebel because it can either set up Calm Minds on a weather setter or Wish + Protect stall weather.
I don't even personally think weather is usually worth running because of how inconsistent it is, let alone banworthy.
From my personal standpoint, i use weather quite often and I like to feel like I know the ins and outs better than the average person when it comes down to weather and its proficiency.
I agree, weather is not suspect worthy but, I feel like you undervalue its capabilities here, and don't validate what it's actually good at.
Weather doesn't like to play TSpikes + Kanga, Stall and Bulky Offense with the Correct counters, that is 100% true.
Weather loves to play against pure offense. And what does Offense have for weather, priority, fake out, uhm, that's it? And Weather is, by far, the most proficient way of beating offense teams and let's have a look what teams are being used most right now? Offense to Balance. People running around with Stall atm are at an all time low due to how wallbreak happy and offensive the meta is, which plays right into the weather users hands.
And between all the weather abusers you have, making the most of just one can tear apart a balance / stall team. Don't forget, there is a trade off in running stall vs weather in the fact that it takes much more to kill the weather setters meaning weather is up for longer, whereas with offense you are only really getting 14 turns to abuse weather, if that.
To finish this off, I'm gonna say that yea, weather isn't suspect worthy because it isn't broken or centralising enough to warrant a suspect test or even ban. But, if we look at this in the bigger picture, maybe if we ban the damp / heat rock, we will have a more fun meta, since offense isn't at such a huge disadvantage playing another playstyles.
And let's not forget, weather is getting
more popular, and not the other way round, so the argument that weather isn't popular enough to warrant a ban isn't the valid reason you are hoping for.
