Dude, calm down...I was just responding to one of maybe five people trying to refute my analogy instead of addressing the argument.
Also, yes, it does. Have you played
any 4th gen UU? I said this before: the main thing holding Rain back was that it was temporary and required setup. No one could get away with Rain in OU because Tyranitar and Hippowdon could switch right in and cancel it out. Even Abomasnow, for those who ran Hail stall. It always took an extra turn to set up the rain.
Now in 5th gen, it takes no turns to set up Rain. The second Politoed is in, Rain is in effect, which gives me a free turn to do whatever I want (like attack). Once Politoed is out, I can switch straight into Kingdra and start causing damage.
Example: Beginning of the match - Politoed and another lead are in. Rain starts.
Turn 1 - Switch to Kingdra.
Turn 2 - Attack
or:
Turn 1 - use Hydro Pump. Tyranitar/something else takes massive damage trying to switch in. You now have the advantage.
or even:
Turn 1 - Use a status move. Tyranitar is now either asleep or poisoned. You now have the advantage.
Without Drizzle: Uxie and another lead are in.
Turn 1 - Uxie uses Rain Dance
Turn 2 - Lead uses Stealth Rock
Turn 3 -
Tyranitar switches in and cancels out the rain.
Turn 4 - Switch to something else to set up Rain (which takes a hit from Tyranitar)
Turn 5 - Tyranitar switches out while you turn on the Rain
Turn 6 -
Tyranitar cancels out the rain again.
^ Do you see how many turns you wasted trying to get and keep the Rain up? This is really hard to do and wastes time when you could have just used a standard offensive team and started doing damage right away. 4th gen Rain didn't work in OU.
UU was a different story. All it had to deal with was Snover and Hippopotas, neither of whom were exactly common. Even if they were around, they didn't have many opportunity to switch in, save for revenge, and weren't exactly threatening to anything while they were in.
But even then, there just weren't enough UU players convinced that it was broken for it to be banned. As long as we could wall/cripple/stall them out for eight turns, it was usually easy to get a powerhouse in and sweep the team afterward.
Also, every turn your opponent spends switching in a Rain Dance user as well as
using the move was a turn for you to initiate your own plan of action. For a good example, read this warstory:
