Thorhammer, can you please stop already? Aldaron's proposal passed because it was the best way to keep both Drizzle and the SSers in the metagame, not because weather is something magical. All other problems with weather are due to INDIVIDUAL POKEMON, who can be banned INDIVIDUALLY without any need for complication. The only reason it existed in the first place was that by the old rules Politoed would have been banned by Support, but at the same time it offers a lot to the metagame. Nothing else works like this. Please stop. We've all had this same damn argument SO many times.
Read Aldaron's proposal again. The whole reason it was acceptable is because it established weather abilities as being different from other types of complex bans.
However, it's also false to say that the problems with rain were not because of individual Pokemon. Only certain Pokemon - generally agreed to be Kingdra, Ludicolo, and Kabutops - caused problems in the rain. No other Swift Swim Pokemon was broken under any conditions, and therefore they should not have been banned under any conditions.
I'm not giving reasons for an argument I didn't make. In fact, I'm pretty sure Sand Veil + Garchomp is all over my previous post. Call it hunch, but I think you just want to Ban Sand Veil + Sand Stream because it looks so similar to Aldaron's proposal.
In fact, I'm not even going to pretend for a second that I care about missing against Pokemon no one uses, like Cacturne, Sand Veil Dugtrio, Sand Veil Gliscor. There's no need to keep Pokemon that suck from using being able to use Sand Veil, because they suck even with Sand Veil and don't benefit as much from a free turn as Garchomp does.
Instead of using the complex ban to make the ability do nothing, why don't we just keep Garchomp from using it? He's the only Sand Veil user that's causing a problem.
...Okay? Then argue in favor of that. Be sure to include an explanation for why we should ignore the policy that was explicitly made at the start of Gen 5 not to ban individual abilities on individual Pokemon.
As for my argument against it? Garchomp's DW ability has not been released. At this stage, banning Sand Veil, or even Sand Veil Garchomp, means banning Garchomp entirely, which is something we should not do, as Garchomp is not broken. Even with Sand Veil, it is not broken.
Then why not ban Snow Cloak too?
Because it's not a problem. It's only 20%, and it's nullified if the weather's changed. It's just as haxy as a crit or a flinch.
On my Hail Team, Snow Cloak helps my Froslass dodge maybe one move every two or three fights. It's helpful, but hardly broken. I imagine that's the case with most Sand Veil users. If it turns out that Garchomp is OP because of it, then either ban Garchomp or ban Garchomp with Sand Veil (though with the latter, you're getting into too complex bans). Personally, I haven't had trouble with him, but then again, that's probably because I run a Hail team.
I am advocating for both a Sand Veil + Sand Stream ban and a Snow Cloak + Snow Warning ban.
We aren't talking about what's broken. We're talking about what violates the Evasion Clause and causes a purely negative impact on the metagame.
Something passive has a small, 20% chance of activating.
Something that requires moves has a much larger percent chance of happening.
Makes sense to me. Using the Turn Iron Heading a paralyzed Pokemon for a little better than a coin flip for a free turn, or not doing anything for a tiny chance for one at the requirement of needing to use a slot for TTar or Hippo. It's just.... different.
Really, there's nothing wrong with Sand Veil or Snow Cloak, people just are mad salty against Garchomp because of Gen IV. Grow up, people.
It makes sense, but that doesn't make them automatically equal. Furthermore, when a passive ability causes a 20% chance of any attack against a Pokemon missing, regardless of the Pokemon's actions, that's far from a small chance.
I have no bias against Garchomp. In fact, I think its reintroduction to OU was an excellent addition to the metagame. However, when it is paired with Sand Stream, it stops being an excellent addition and instead becomes a luck-based one that detracts from the metagame.
