I'll take a shot at the questions in the OP for a bit. Then I'll really dig into this thread when I'm not at work.
- Is Baton Pass (with specific reference to full Baton Pass teams) a problem for the development of the metagame?
Of course not. Really, a BP team archetype is hardly different from stall, hyper offense, balance, trick room and even weather teams. You might get a few mindless wins here and there, but if you're uneducated about the threats you have, you're going to be getting more Ls than Ws. Just like any playstyle, it has its strengths and weaknesses. I don't really subscribe to the idea that the match is decided at Team Preview either. However, if it was, you know what that would require?
Knowledge of what your checks and counters are and how to beat them. Why is this something that should be punished? If anything, learning how to overcome your weaknesses should be basic knowledge for a skilled player.
- If so, what elements, in particular, do you think are pushing Baton Pass over the edge?
I think a few things are getting people to at least think about it. Scoliopede is the biggest thing. The Eeveelutions in general are also a big part of it. All of them have stored power and heal bell, five of them have type immunities and three of those get boosted by eating said immunities, three of them are really bulky, one of them is godly fast, and they are mostly pretty good special attackers. There's also Magic Bounce which stops setting up passive damage in its tracks. However, the thing to key in about all of this is that it all tends to
make BP teams generally predictable. The fact that many viable BP users are Eeveelutions is a double edge sword. For the most part, they all have lousy movepools, and they tend to overspecialize. They have one or two things that they're REALLY good at, but they don't have much outside of that. Seems no different to any other archetype really.
- Do you believe that banning individual Pokémon (such as Espeon/Scolipede) would make Baton Pass manageable?
No. I actually don't use Scoliopede in my BP team. Speed boosting is left to getting Agility boosts, which is a challenge in itself. Additionally Scoliopede gets WRECKED by Talonflame. There is literally nothing be can do and leave in one piece. He can protect all he wants, but he's taking a BB BEFORE he sets up Iron Defense, and then he's taking one BEFORE he baton passes. Then whatever he brought in is also taking a BB unless it's like, Mawile or something. Espeon is pretty frail without defense boosts itself. Not only that, but it's weak to Knock Off which is literally everywhere. Additionally, being an Eevee it's fairly predictable. It's either going to be dual screening, or boosting to power up stored power. Furthermore, it can't run Stored Power, Dazzling Gleam (for Dark types), AND HP Fire (for strong bugs), while still carrying CM and BP. Once you figure out what set it's using, it ought to be simple enough to dispatch.
But even if you DO ban those guys, there are others that can do the job that they can, or the BP user has to get more creative.
- Would you support a blanket ban on the move Baton Pass?
Absolutely not! Yeah I run a BP team, but like I said, I WORK for all of my wins. Every W I get that isn't a forfeit is truly a "super mega win" in my eyes. Furthermore, BP teams aren't the only ones to use BP. What about dark weak mons trying to avoid pursuit. What about quick boosts?
- Would you support the introduction of complex bans (like Pokémon X+Pokémon Y on the same team)? Feel free to suggest more forms of complex bans, of course.
Definitely not. Using BP requires just as much knowledge as any other playstyle, and in many cases is considerably harder than some others. Honestly, it really really feels like people are set in their ways, and want to ban everything that they can't beat with their old tactics. What happened to evolving and adapting to new threats? Every team is not going to beat everything. No matter how good you get, there will always be someone better. You win some, you lose some. It's all a part of the game.
