Well, there isn't exactly proof, but from the look of things, it does seem like sand is more prevalent than rain is. Another thing, people will disagree with this and I can understand why and I agree to a certain extent, but the PO statistics also show that Tyranitar and sand is played more than rain. The metagames are somewhat the same, but its the closest thing there is. We'll just have to wait for statistics for Smogon I guess.
How diverse the metagame will be without rain we won't know. However, if you ban drizzle, that just completely shuts down a whole weather archtype. Basically everything you can play with after drizzle is banned can already be played with drizzle around. Sand will still be at the top if rain is banned, so are you going to ban sand next? Rain dance just doesn't compare to permant weather. Also the whole "fun" thing you should just stop talkling about. It is solely based on opinion, and it varies with different people. People could say this metagame is more fun than gen 4 metagame, but it has nothing to do with anything and is just opinion and how you feel.
This is not a "rain" metagame. It is a weather metagame. Rain doesn't dominate everything all the time so it can't be called a rain metagame. Also, the group isn't small I suppose, because if it were, then drizzle would have been banned already since the suspect votes for banning and keeping drizzle were almost half and half with a few more on the banning side.
I know this is long, but please read the whole thing to prevent looking stupid if you quote it.
Sand, the best counter to rain, is of course going to be more prevalent than the thing it counters. It was also around before drizzle was, so more people are used to it.
I completely disagree that everything you can play with drizzle banned is playable now.
As is stands, everyone has 1 of 5 weather inducers, uses their manuvering to kill the opponent's 1 of 5 inducers while losing as few pokemon as possible, then uses the boost they get from their said weather with the last set of about 9 pokemon (manaphy, kingdra, kabutops, landlos, dory, tek, tangrowth, venusaur, and shiftry) which have only a specific set of counters that were on each team already to counter the opposite type of weather... leaving us with 20-25 actually useful and used enough pokemon to call OU (there are very obvious patterns on teams as to counters and support). Weather itself causes centralization because it is free and powerful with a small range of counters.
Getting rid of drizzle only fixes part of the issue, and in fact may cause a larger issue as it will let sand up from its most notable opponent. The fact of the matter is that
as long as there is a weather that auto-boosts semi-permanently speed and/or damage on a pokemon, the metagame will be extremely centralized around it. My suggestion, as stated previously, makes it so each weather is still viable, just requires a turn to use and a more diverse and less predictable team to pull off. If we drop sandstream, drizzle, and drought, they will all still be just as viable in comparison to each other, but will create a larger and more stable metagame where there is an abundance of play styles, strategies, and probably still a good amount of weather.
The problem now isn't that I'm crying over a change to a weather meta. The problem is that a weather meta allows for minimal diversity
not only in pokemon choice but in play styles. To keep this type of meta would make anyone who wants to use any pokemon outside of that small set play UU.
Also, I would prefer if you all would wake up and realize what I mean here. Its not a question of if auto-weather is
overpowered, as it has obviously taken complete hold of the meta. The real question you need to fight against to prove that auto-weather is fine is my statement that it is
over-centralizing. What would you say is the size of the pool of usefull pokemon right now?
5 auto weather+9-10 sweepers+10 reliable counters? (from reading along the post) This would bring us to every team running 1-2 weather, 2-3 sweepers, and 2-3 counters for other weather.
Now, with this in mind how does a player win? by destroying the opponent's 1-2 weather users before they destroy yours if the opponent uses a different weather. By using 1-2 of your counters to fend off the same weather type.
Where is the diverse set of playstyles normally associated with strategy? To me this sounds more like playing Modern Warfare 2, where you all use the same small set of guns with the same set of perks (abilities) and it all just comes down to who plays the single most powerful style the best.
Neither rain, sand, nor sun are broken if the weather lasts only 5 or 8 rounds. Much of the problem stems from being able to switch to a counter, wall an opponent's sweeper/counter with your counter, and much later switch back to a sweeper without even needing a turn to change between. It is literally normally a win to whoever gets their weather up last.
Having an unexpected pokemon with a random weather also isn't very viable in this meta, as you'll need to utilize that weather pretty fast to prevent a sweep (unless you're using those 10 counters, in which case this solves nothing for the meta), and then they see your weather inducer the same as any other, but with a 1 turn handicap that makes it much easier to kill. A single pokemon also can't counter each weather with a type that would benefit the team in another way, since hail is the only real choice to stop all the boosters.
Weather balances out nicely against itself. The problem is that there's maybe 3 play styles, and 20-25 viable pokemon (meaning pokemon that aren't outclassed by another at making, abusing, or stopping weather... as is another common reason for the change from ou to uu). OU is about not being centralized, and having a variety of play styles and a large pool of pokemon that is even sometimes able to dip into the UU pool for specific situations. This current meta has absolutely none of the characteristics of a good metagame except for partial balance.
Edit:
I forgot to mention, but I was mostly agreeing with the quoted post xD banning drizzle alone does very little to help the meta. (though that last statement, it was 58%.... but no one veted against ban, it was either abstain or ban.)
