I'm just posting to say that I don't think we should be making any sort of official retroactive ban on Baton Pass. This is several years after the fact, and there is no point to doing such a thing. As I've said throughout this thread, Baton Pass is not broken, just currently unhealthy for the meta. I will illustrate what I mean by this in this post.
In supporting this Ingrain Smeargle ban, I support it for this rendition of this tournament only. I believe that after all this is said and done, BP will not be particularly hard to integrate into the metagame, as it is not inherently broken. Yes, it does require an explicit check, and is as a rule extremely unforgiving, but so are DDTar, Curselax, Heracross and many other iconic ADV threats. It's the nature of Baton Pass which makes it so ridiculously hard to beat if you don't have one of those counters (as opposed to those three above, who can feasibly be muscled through or critted down), which makes not being prepared for it so unhealthy for our competitively-natured meta. My reasoning behind not allowing it in this tournament is that it's not healthy for the meta as it stands, because it has not had time to be integrated explicitly into the meta. I hope (and believe) that in the future, Baton Pass would not be such an issue once we get over this honor code that seems to be a common notion. As it stands, we're simply not over it, which is what makes a temporary ban so feasible for a highly competitive setting that will involve the entire community, not a permanent ban.
Additionally, the precedent that making this permanent would be setting for retroactive tweaking is something that there's no need for Smogon to jump into right now. Those metagames are so fun for many because they are frozen, static metagames where people don't have to learn as much: they can be competitive just by reading old warstories and analyses. What worked when DP came out will still be working today, because the meta stopped advancing. If we are to alter that, we certainly should not approach it with our current mindset, and definitely should not do it while the twotone gen's ban policy is such an issue.
This really segways into what I would believe would be a good topic for us to decide on before we do make decisions on any permanent ban: the ban policy in general. I won't recap the "Lifting the Burden of the Rulemaker" and "Banning in Gen 5" threads here, but suffice to say, we as a community should determine what our objective point for metagame formation is overall, and especially for the current generation, before we tweak retroactively. However, overall that goes outside the scope of this post, and I only bring it up in closing as support for my point. I don't mean to start any sort of "retro tweaking debate" here, but I do think the larger issue of retro tweaking in general holds this thread inside it, and should be addressed in the future, once this tournament is no longer the scope for this debate and future retroactive debates.
But to reiterate my point: Ingrain Smeagle should be banned ONLY from this tour, not on any merit of brokenness, but because as a whole, it is unhealthy for the competitiveness of the metagame, largely due to the mindset that BP shouldn't be used that seems to be in place. I never really understood that to be an explicit "honor code", but now that I look back at the state of the ADV game, it would explain why BP is not integrated into the meta. That makes this "mental block" of BP the main thing to overcome once this tour is over, to prevent any sort of permanent retroactive ban from taking place.
(I will recap why BP is not broken if you really want me to, but at this point, anyone who has been playing on ladder should know by now that BP is breakable if you know what you're doing and are ready for it.)
