For those who claim Scizor, Ferrorthorn, and Forretress abuse rain, that is not true. They don't have anything to abuse rain, they just are less weak to fire, and frankly, if you can't OHKO them with a 2x effective, you should probably change your team a little. Timid Genesect with flamethrower and 252 Sp. Attack Evs OHKos all three in rain, which means Salamence, Chandelure, and tons of other things can still OHKO. Breloom is more of a rain counter than abuser. The only way Dragonite can abuse rain is a special set, and Blissey and Chansey troll all over it, not to mention the fact that it's pretty slow. Thundurus is amazing without rain anyway. Thundurus still gets walled by the pink blobs, and even if it kills Hammer Arm, it's almost asking to be outsped and killed. Rain is the only thing from keeping sand from dominating the metagame, and no sand abusers have been banned. Rain is not broken. The huge amount of water pokemon can basically be killed with TBolt and Grass Knot.
