>>55733153Normal was the strongest type in Gen 1. Tauros, Chansey, and Snorlax are considered the top 3 best Pokemon in standard play. Hyper Beam got nerfed through the ground because of Normal's sins.
It's still incredibly easy to have perfect neutral coverage with Normal. Of the 3 types that are resistant or immune to Normal, 2 of them are weak to Fighting, none can resist Ground without a secondary type, and Dark gives Normal coverage for everything that isn't Lucario, Cobalion, Terrakion, Kingambit, Tyranitar, Diancie, Carbink, Mawile, Zacian, Magearna, and Tinka75.
