You don't like how your team works under Drizzle? YOU CHANGE THE WEATHER OR YOU CHANGE THE TEAM. You use your Tyranitar/Hippowdon/Abomasnow/Ninetales (or even Vulpix/Hippopotas/Snover; nah just kidding, don't use them cause they're shit). Or, you run a weather move. Either/or. Not adapting to weather just because you don't want to use weather yourself doesn't mean that weather is broken, it means you should SUCK IT UP AND USE WEATHER. Or don't and be good enough to get around it. Or you could join one of the 5+ other Pokemon metagames that don't have weather domination.
What other weather beats Drizzle? Hail? Stealth Rocks manhandles Ice types and Abomasnow can't switch into STAB Hydro Pumps repeatedly. Ninetails and Tyranitar both weaken STAB Hydro Pump as they come in but it still hurts. How are you supposed to adapt to something that beats its "counters" so easily and proceeds to rape you with boosted attacks and powerful 100% accurate STAB moves with almost no drawbacks?
Those whole 2 paragraphs above? Not even related to that bolded sentence up top, but this one is; I just thought I'd get that out of the way. You see, when Drizzle comes out onto the field (let's assume the opponent starts it), nothing happens to the Pokemon in-play. Next turn, you make a move with your Pokemon, your opponent makes a move with theirs, it goes in a certain order depending on what moves you and your opponent have chosen and the Speed stats of your Pokemon including item, ability and stat boosts, each move goes off unless the first to go takes out the second, and the turn finalizes. This repeats until the game ends with a victor. What did Drizzle do on each of those turns? NOTHING. Sure, your opponent's Pokemon might have done something different than usual thanks to Drizzle, but that's just it; it was the Pokemon doing it. Not Drizzle.
It was the Pokemon that let Ferrothorn or Jirachi set up all over your Magnezone? I don't think so. -.-
In this sense, Stealth Rocks is more broken than Drizzle, seeing as, improbable as it may be, without a Magic Guard Pokemon on the team you could theoretically be 6-0ed solely through SR damage. Sandstorm, Hail and Spikes could do the same, but at least for those you have the pool of Rock/Ground/Steel/Ice/Overcoat/Flying/Levitate Pokemon to choose from as well respectively, but SR? Nope, just the 3 fully-evolved Magic Guard Pokemon and their pre-evos. But this isn't about SR being broken, cause it isn't; it's about Drizzle being even less broken, so it's not broken either.
How are Drizzle and Stealth Rocks even comparable? Nothing can stop Drizzle from being played other than three really uncommon moves and the weathermons. Stealth Rocks is prevented by Taunt, Magic bounce, Magic coat and can be spun away. Don't forget that there are also plenty of resists to Stealth rocks holding leftovers which cancels out the damage done. Therefore, you're wrong about only magic guard Pokemon stopping SR from 6-0ing a team "theoretically". Conkeldurr, for example, or even Bronzong prove this.
Also, pretty much every argument on a Pokemon being broken has said something to the likes of "This Pokemon O/2/whatever-HKOs that other Pokemon with SR damage". Why the hell aren't we just doing this with the weathers? SR and weather are close to mechanically identical, with SR directly damaging Pokemon (differing in how much based on certain criteria, such as typing) and weather boosting Pokemon (differing in how much based on certain criteria, such as typing). If you consider weather as a field condition, like it should be, then tiering becomes much simpler, as we skip all this "what's actually broken" shit and get straight to Pokemon bans. All those Pokemon that are broken because they are boosted by Drizzle? They are unlike the rest of the 649 Pokemon in the game that aren't broken by Drizzle, which means they should be treated like those few Pokemon broken regardless of Drizzle, and be banned. Simple.
No, they are not even close to identical. Stealth Rocks only takes effect when you switch in a Pokemon on it. Drizzle lasts the entire match and boosts attacks for the entire match including the turns you don't switch a Pokemon in (unless you switch in a weathermon which is taking lots of damage).
Also, while reading this thread, one post has stuck in my mind for something within it. I can't be bothered to find said post and confirm it even exists, but I believe it said something along the lines of, "Drizzle makes OU-worthy Pokemon broken, and non-OU-worthy Pokemon OU-worthy, so Drizzle should be banned". OK, Imma gonna go ahead and break this in half:
1. Who decided that said Pokemon were OU-worthy? If they are broken under Drizzle, then they are broken and above OU. There is no "OU-worthy" for anything, not even for Starmie and Gengar, and to say that anything is inherently "OU-worthy" shows a bias unfit for a competitive decision.
2. ...And? Some Pokemon that would otherwise not be in OU are in OU thanks to Drizzle. This means there are more Pokemon in OU with Drizzle than OU without, yes? Isn't that a... good thing? Other than that, it's pretty much the same as the above point; why should these Pokemon not be considered OU-worthy if being under Drizzle makes them OU-worthy? They don't just get an arbitrary not-OU-worthy status just because whoever said this that I don't know says so.
You're comparing Drizzle to SR. Therefore, we should treat a Pokemon broken under Drizzle like a Pokemon broken under SR. The two aren't even comparable so what's your point?
tbh, I don't see what you gained from a wall of text. keep it simple. ;)
