Spiega posted...Gen 1 = Psychic/Normal
Gen 2 = Steel
Gen 3 = Water
Gen 4 = Dragon
Gen 5 = Water
At least, to my knowledge.
In my opinion
Gen 1 is both because Normal make up the offense, Psychic make up the supporter
Gen 2 because it is dominant enough to make normals not as good as it used to be and there is no other crazy good type anyway....
Gen 3 because Suicune, but in general Ground is pretty huge as well
Gen 4.... Draco Meteor
I chose Water for gen 5 because the meta has never been as ******ed as the Broken Trio metagame. Even Volt Switch has a rather major water involvements. Fighting has never been a real dominant force until recenty(back then people was like Conkeldurr omg hit so hard, despite the fact that it carried less immediate power than even Machamp in term of common sets. Lol who's laughing now)
So, based on this, I say Water yet again in gen 6 if a massive nerf is not issued. Water is just that good.
