In Gen 6, a Pokémon with the ability Drizzle, Drought, Sand Stream, or Snow Warning will produce the same effect as if it had used it's weather inducing move as it switched in. This means that after the switch-in, the weather effect will only last five turns, or eight if the weather inducer holds Damp Rock/Heat Rock etc.
Possible Effects on Metagame:
-This will make it much easier to deal with speed-boosting sweepers. It is much more difficult to sweep with Kingdra and co when it only has four turns to do anything. Venusaur can now be stalled out, and only has three turns to sweep after using Growth. Excadrill is in a similar boat with Swords Dance, and Landorus will not appreciate it's power constantly having to be renewed.
-Secondary weather abilities and effects such a Dry Skin, Rain Dish, Hydration (yay Manaphy!), Ferrothorn's loss of its 4x fire weakness, Hurricane/Thunder, the uselessness of Fire sweepers in rain, and the power of fire/water sweepers in their weather will be more or less defunct, especially the defensive abilities, which will rely on constantly switching in the Drizzle user.
-Weather wars will be much more interesting. One can see a metagame where non-weather teams try to kill/trap the weather inducer as quickly as possible, while weather dependent teams must keep their inducer alive for as long as possible. Sun in particular can no longer use the powerful "sac Ninetales and trap with Dugtrio" strategy on opposing weather mons.
-We might see some support mons running Rain Dance and Sunny Day, or maybe even Sandstorm.
Altogether, it looks like GameFreak answered the prayers of many Gen 5 players and gave a heavy nerf to weather. How prominent will weather be in the new meta?
