(rofl, I kind of skipped a page before writing my other post, so I'll try this again.)
How is Mence doing, anyway? I've rather fallen out of the loop with regards to his standing in OU vs. Ubers.
But yeah, I agree that we shouldn't just toss everyone into the BW meta for some big bukkake of brokenness. Leave the tiers the way they are when BW comes out. See how OU fares with the dozen or so extra Pokémon that Gen5 introduces by itself and let things pan out for a bit. Then we can start throwing in the old suspects to see how they size up to the newcomers.
Anyway, talking about Triple Battles, do we have the foggiest idea what mechanics they might introduce with them? The scans say that positioning/team lineup will matter in determining how multitarget moves work. Maybe, as an example, Rock Slide can only hit two adjacent targets. So if you happen to have two Pokes weak to Rock out at the same time, put them each on sides and send out someone resistant to Rock in the middle, and then you will reduce the effectiveness of the Rock Slide.
And also, what about having triple leads? Getting down all three layers of spikes down on turn 1?
