finally an argument that isn't just "I realize it's not broken but i just don't personally like it." However, I don't think the argument that sleep clause being removed would deter people from playing holds water—at least, it wouldn't deter the kind of people we WANT playing. Anyone from other tiers who tries out doubles has to approach it with an open mind anyways because it's so different; removing sleep clause is hardly going to be the straw that breaks the camel's back and makes them stop playing. If no sleep clause scares anyone off, it would be the people who try to use OU teams in Doubles anyways or worse, and sue me for not crying if we lose those folks. There's been no evidence that the sleep test has scared off potential Doubles contributors—this test has drawn far more people than the first Suspect Test, and most of them have been saying that sleep isn't broken, despite having never played the meta when sleep clause was here!
I have to say that I have never played Smogon Doubles for the sole fact it has sleep clause on. Not that I like to put everyone to sleep, but because a strategy that I often use is to induce my foe to think I'll try to abuse sleep and this way I can focus on killing everything while he is trying to bring my sleep inducer down. I was out of the forum for a while, so I didn't know about the suspect. I have to test two teams for a tourney this week, but you can be assured that I, for once, will get back to Showdown and create a Doubles team as soon as next week, because I'm thrilled to see this thing out.
And that's exactly the thing I preached. Sleep clause complainers are OU players who don't want to adapt purely and simply. And they hurt the metagame much more than the good they bring by being there.
