You are correct. Simply using Roar or Haze or any other move does not guarantee a win against Baton Pass teams. But what makes a Baton Pass team so dangerous? The ability to pass stat boosts from one Pokemon to another while accumulating more, gradually working up to become damn near impossible to KO.
However, if you disrupt the Baton Pass chain, if you force your opponent to reset and start building his boosts again, or better yet, don't allow them to build up in the first place by applying pressure from turn 1, then you are at an advantage. Granted, I completely agree that this is not a game-winning advantage. But you can wear the Baton Pass team down if you can negate what gives them an advantage- the passing of multiple stat boosts. Please keep this is mind during any eventual suspect testing.
The thing is you cannot stop them if that mon is gone (All MB Roarers loses almost embarassingly quickly to Sylveon), this means you'll have to run multiple obscure counters to a single playstyle, which isn't even a playstyle, doesn't that worry you a bit?
Hiphiphooray
Dude, my eyes are permanently stuck rolled back, BECAUSE YOU STILL HAVEN'T GIVEN US ANY REPLAYS!
We're discussing things that almost all the top players agree on, and then you come in and make us explain things that even I understood pretty instantly. Since the people that matter most as far as smogon is concerned (see the switch to 1760 stats discussion) are the ones who picked on BP's terrible potential effect (and current effect) on the meta, you're the one who needs to give proof.
You've been at this for 12 pages, and all you've succeeded in doing is making this baton pass business even more miserable than it has to be. Until I see replays, I'm going to assume you haven't been on the ladder (I looked up Hiphiphooray, and it has an ELO of exactly 1000, so I desperately hope that's not you), so I'll let you in on a secret, EVERYBODY HATES BATON PASS! Forget all that pointless discussion about auto-losses and counters and crap, if something makes the game less fun to play, why would we keep it. This is our meta game, our rules, and our time that we're devoting to it, so I don't think we really should need a reason to ban it.
Now I can imagine the response I'll get for that, but I really don't have much to add besides, nobody (intelligent) claims BP has no counters, it just has so few OU viable counters, that people won't consider limiting their team building options just to take care of BP. This allows poor players to rank rather easily, which is of course unacceptable. But now, thanks to this thread and the general attention BP has gotten, more people are using it, and more people are forced to use counters, or teams less susceptible to BP, and they're losing to people who are equal skill level, but haven't compromised their team for BP. A metagame that is decided less by decisions you make and more by the lucky match up* sounds terrible.
*note, I'm not trying to suggest that it's an auto loss, just significantly less competitive than the accepted meta game.
This is the fundamental of what happens after consistently being forced to rebuke what, in reality, is a very simple concept. Baton Pass is the definition of uncompetitive, almost in the same vein as Swagplay. It applies a feeling of helplessness because it not only requires NO skill to utilise, but gives no opportunity to turn match around, hence why most BP battles end in forfeits rather than wins/losses. The only reasons that have been made by the no-ban side have said "the metagame has to adapt" or "Just because its counters are unviable now, don't they become viable if people use them?". Although I expected this to happen, this thread has just degenerated into a cesspool because users of a particular "strategy" don't want to lose what gives them wins without requiring effort (I'm talking about BP users, in case there's any confusion) and are willing to spit out anything that has the smallest chance of changing peoples opinions, very similar to the Mega-Luke discussion.
I really think this thread needs to be moved to VR. Even though it means I don't get a say, it stops people who clearly are grasping at straws from bringing down the IQ of everyone else in this forum.
