Actually, snow warning banned in OU would not ban it in UU too. Somethign weird has happened like that a few times before, like when wynaut was banned in OU, but legal in UU.
There was a thread in PR earlier this year very explicitly explaining why to avoid that policy, and I believe that is the decision that has been kept. The Wynaut thing doesn't sound right, either, as there was never any reason to ban it from any tier, so it would never be specifically banned from OU but allowed in UU. What you may be thinking of is that Wynaut was allowed in LC, which is entirely separate (although it makes you wonder how the hell Wynaut was never unbanned before this gen when that very explicitly proves that it was not broken anywhere).
That's a very good argument. Similarly, no one in their right mind would argue that Excadrill is broken without Sand. No one in their right mind will argue that Espeon is broken outside of BP teams.
So, IF it is broken, what's the solution? Ban Espeon and Baton Pass? That's very complex. Ban Espeon entirely from OU? Espeon will never be used again, because I don't see how it can do anything in Ubers. Ban Magic Bounce? That's an idea.
Banning Magic Bounce doesn't sound right, as it is clearly not broken on all reasonable Pokemon - see Xatu for an example. However, I realized reading this post that, if there is something broken about Espeon's role on Baton Pass teams, then the combination of Magic Bounce + Baton Pass is quite plausibly broken on all reasonable Pokemon, because it would allow any other Pokemon to do much the same thing, and it would be that combination that should be banned.
Honestly, none of those are broken individually, so I don't see how it's right to ban one or the other.
So, what's wrong with another complex ban, magic bounce + baton pass? They've already done it before with Drizzle + Swift Swim, why so reluctant to do complex bans?
Indeed. People do not seem to understand that a properly designed complex ban requires less need than a corresponding simple ban of one of the two elements, not more, as less is being banned.
While I still maintain that the Drizzle + Swift Swim ban was an incredibly poor choice in the face of alternatives, the same principles behind it can be used to make other complex bans for the benefit of the metagame, including more suitable alternatives to the original ban of Drizzle + Swift Swim. In particular, we should not be reluctant to ban the combination of a specific Pokemon + Weather.
meh, i guess i must have the necessary tools, when i see a baton pass team i stop it cold most of the time, especially since sableye has been released (ninjask<<<<<<<<<<<<<<<<<taunt) and if espeon comes in to ruin my fun i hit it with foul play (despite the low attack espeon has it still deals a shitton of damage)
Seems that Whimsicott, Tornadus, Thundurus, Murkrow, and now Volbeat and Sableye can stop a Baton Pass team cold at any time Espeon is not on the field with Prankster Taunt. This is very much worth keeping in mind when considering whether or not it's actually broken.
Also, Murkrow and Sableye are immune to Assist Power, and Murkrow has Perish Song.
