3) The majority of available rain abusers require Rain to be up to be "OU Material."
That's a pretty big assumption to make there. Have Zapdos, Empoleon, Gyarados, Starmie, Rotom-W, Scizor, Suicune, Jolteon, and others suddenly become "not OU material"? This assumption loses ground when you realize that "Pokemon that abuse rain" is not just "Pokemon that have abilities that work under rain" but also "Pokemon that can utilize an extra STAB for Water attacks, 100% accurate Thunder/Hurricane, extra Fire resist, and lack of Sand, Sun and Hail, among others".
And before you say, "well, then why not just use a normal team instead of burdening yourself with Politoed", I will just say that this is why other weather teams work; they use what they have to their advantage. The only difference between Rain teams and other weather teams is that Politoed is weaker than the other inducers; hell, he could be a better asset to Rain teams than Ninetales and Abomasnow are to Sun and Hail (that last bit's speculation on my part, you can ignore it if you feel otherwise)
This is also assuming that Politoed is not OU material. The thing is, there's really no such thing as "OU material"; if enough people use Politoed solely for Drizzle, then Politoed becomes OU. Simple. Politoed's niche is bringing Drizzle to OU; if that's all he is, then so be it. It's still his niche.
Finally, I'm still not sure where this "fewest bans" thing came from. If someone could point it out for me, I would appreciate it, because it's not in the Smogon philosophy I found on-site. Regardless, I feel that banning something that isn't broken solely for simplicity and the fewest bans isn't what we should be doing. We should be banning things when they are broken, and Drizzle CANNOT be broken in and of itself. Maybe it fits under the Support Characteristic, but the fact is, Drizzle can only provide itself to break other Pokemon; it's not winning the battles, the Pokemon who utilize it are.
EDIT:
I don't really care that you have this opinion. What I'm talking about is people repeating fundamentally different views as if this will somehow sway opposing fundamentally different views to their side.
The thing that I don't like about the Luvdisc argument is that Luvdisc effectively doesn't exist in OU. For this reason, I could come up with, or even make up, any contrived hypothetical to "prove" or "disprove" a point and it would be at least as valid. The other thing is that you're using the statement
1. {Ability} breaks {otherwise bad Pokémon} => {Ability} is broken
to describe Inconsistent, but when applying it to Drizzle, the natural thing to do is to claim
2. {Ability} does not break [otherwise bad Pokémon] => {Ability} is not broken
and though you didn't make that certain conclusion, had you done so it would have been an obvious fallacy because 2. is the converse of 1. so it does not follow from 1. So really, the premise of 2. doesn't demonstrate anything other than the uncertainty that was the whole point of this undertaking.
If it does so happen that some Swift Swimmers other than the eternally bad ones aren't broken but still viable, then that is the only scenario in which banning Swift Swim and banning the abusers aren't essentially equivalent.
Ah, ok, I understand where you are coming from. I've also grown tired of the repeating arguments (though from my posts, maybe that's hypocritical of me)
I can also see where you're coming from there.
Thank you for pointing that out. Would this logic chain be better, or worse?
1. Pokemon A is terrible -> Ability A is the only new thing applied to Pokemon A -> Pokemon A is now broken -> Ability A breaks Pokemon B, C, and D as well -> Ability A is broken
2. Pokemon 1 is terrible -> Ability 1 is the only new thing applied to Pokemon 1 -> Pokemon 1 is still terrible -> Ability 1 breaks Pokemon 2 and 4 but not 3 and 5 -> Other factors or a combination of factors break Pokemon 2 and 4 -> Ability 1 is not broken
Essentially, that may be true, but there's also the possibility that non-Swift Swim Pokemon are also found to be broken. It seems unlikely, but it could be.
