besides i don't really think damage calcs on chansey of all things are relevant in the current metagame. we need to be looking at the actual nature of the bw2 metagame in order to properly analyze what's good and what isn't. right now ou is centered around an offensive mindset, with pokemon such as scizor, keldeo, latios, terrakion, and garchomp heading up last month's usage stats. look at those five pokemon. four of them outspeed and ohko hydreigon flat-out, and the other one still does a hefty chunk with choice band bullet punch. i realize these five pokemon aren't entirely indicative of the metagame, but you get my point. right now, hydreigon's too slow and is weak to far too many common attacking types to be effective. base 98 speed frankly doesn't cut it in today's metagame. more than half of the pokemon currently in the top 20 of the usage stats outspeed and ohko hydreigon, or tank a hit and ohko back. that's pretty bad considering what hydreigon's trying to accomplish. fact is, the thing can't fulfill its supposed role as an effective sweeper or wallbreaker because it's too slow and too frail to keep up with the offensive nature of the bw2 ou tier.
