Having read over the thread, I'd like to make two proposals to help us handle the concept of brokenness going into the XY generation:
1. Keep the current ban list, add XY's cover legendaries, allow all other pokemon in XY to come in unbanned.
See pwnemon's post where I'm coming from this. Most of our current ubers are that way because they are simply monsters who have an amazing combination of BST, Ability, Movepool, and Typing which makes them go above and beyond every other pokemon. The cover legendaries, with the sole exception of Kyurem-B, have always been this way. Other legendaries have been a mix of great, bad, awful, superb, and broken, but the covers have almost always been broken. And even Kyurem-B is absolutely superb as a Pokemon. I don't see any reason why we should initially allow them into the tier as history has shown it is extremely likely they'll just be broken as shit. I don't really think a 670+ BST blanket ban would be a great idea, but that might work as well.
2. Doubles Council
As it stands, every single tier on Smogon has a council. I think that Doubles starting off XY with a Council would be extremely helpful, as it would provide us with an emergency "oh shit" team who would be able to call for an emergency suspect test if need be. The reason why I am specifically proposing an elected Council/Topic Leader is because historically, Smogon has always adopted a policy of nepotism, which while thus far has been mostly successful, is still rifle for abuse which we have been lucky to have not seen thusfar. The aim is to prevent such abuse before it occurs.
The specifics of my proposed council are:
2a. One Tier Leader
The Tier Leader would be the head of the council, in a sense. Voted in by the Council once every twelve months, or earlier if the council nearly unanimously votes for a new Tier Leader, the Tier Leader would be responsible for keeping the Council in check and ensuring that the tier runs smoothly. The Topic Leaders powers would be one vote on the council (except during Tier Leader impeachment), the ability to propose any suspect, to propose any policy change, to veto any policy changes, to veto any suspect, and to call for the impeachment of any member of the Council.
2b. Eight Council Members
The Council would be voted in once every six months by the C&C team, or possibly any users who have proven themselves to be worthy of voting via qualifications that can be decided at a later date. They would be responsible for running the tier and ensuring that the proper suspect tests and policy changes occur. Their powers would include voting on suspect proposals, policy changes, and impeaching the Tier Leader or a fellow Council member if need be. They may only override a veto via unanimous vote.
2c. Policy Changes
For a policy change to occur in the first place, it must either be proposed by the Tier Leader, or a council member must motion for a proposal that is seconded by at least three other council members. At that time, a corresponding thread will go up for review, where both those for and against the proposal may debate on it, and where any amendments may be proposed. Access to posting in these posts will be strictly on a earned basis, via requirements that again can be decided at a later date.
2d. Suspect Tests
For a suspect test to occur in the first place, it must either be proposed by the Tier Leader, or a council member must motion for a suspect test which is seconded by at least two other council members. From there, a Suspect Test will proceed in accordance to Smogon Doubles policy. After a Suspect Test has ended, a two to four week period of time for the metagame to settle will be allowed, during which only Emergency Suspects may be called. In addition, Suspect Tests may not be called unless both the Tier Leader and at least seven members of the Council agree that the Tier has settled to the point where Suspect Tests may be held.
2e. Emergency Suspect Tests
Any suspect test before XY Suspect Tests are opened or during the Suspect Test cool-down period is considered an Emergency Suspect Test. Both the Tier Leader and at least seven members of the council must call for a Emergency Suspect test before one may be held. Emergency Suspect Tests will have more stringent voting requirements and will require a higher percentage then usual to be banned, in order to both prevent abuse and help reinforce the seriousness of an emergency test.
2f. Impeachment
In order for an impeachment vote to be called, either the Topic Leader must call for the impeachment of a Council member, or at least six members of the Council must call for the impeachment of the Topic Leader. At that point, an emergency meeting will be held over IRC, after which a vote will be called. For a Topic Leader to be impeached, a nearly unanimous vote of seven out of eight council members is needed. For a Council member to be impeached, at least seven votes between the Council and Topic Leader are needed. The member for whom impeachment is called for is not allowed to vote.
Do note that the administration and moderation teams would still exist as per usual, and if need be the site staff can always step in.
