Well from what I see the way we need to go from here is as follows:
1.) The council should remain in power (because letting anyone nominate suspects clearly didn't work) UNLESS another method of choosing suspect nominations can be derived. I feel, however, that doing so could be rather time-consuming, and that the problem could be fixed with less difficulty by making the council less "secretive". This could be done using the public IRC chat that jabba spoke of, having a public forum that only council members could post in, etc. If there are any mass disagreements with nominations, then they can be voiced similarly to the way this one has or by other means (talking to aldaron for example) and then we can work together to go from there.
2.) We should vote as a community on which "suspect path" we choose to travel down. By suspect path I basically mean how we're going to go about testing a potentially broken strategy. So in this instance, we vote whether or not to test drizzle as a whole or to test individual Pokemon. If we then go ahead to test drizzle and find it not broken, then we can then go ahead and test individual Pokemon (Keldeo, Tornadus-T, etc.) Of course choosing who takes part in this vote can be determined in many ways—though I think the "Glicko2 rating of 2000+" method works pretty well for that. Also, I believe that the council should have more power over the vote. Perhaps they can block a certain suspect path if all members are in agreement.
I'm only spouting out ideas here; there are of course multiple potential ways in which this can be issue can be solved, and I'm not the one making decisions. Just my two cents.
