Instead of complaining about Chansey not getting banned, why don't you all just come up with creative ways of beating it? You might find that it's not so hard to deal with after all. Especially with Drought and Kyurem gone, that's a lot more free space you'll have on your team in the coming month or so of the metagame. Use Knock Off, Taunt, Wobbuffet, Dugtrio, Toxic Spikes, mixed attackers, mono-fighting, physical sets on pokemon that are usually special (like the Swords Dance Celebi I used in the first round of testing), etc etc. There are tons of ways to get around Chansey and now that the two biggest offensive threats are gone I think Chansey won't be much more of an issue.
