Hey you know? I think Genesect should be brought back to OU. Specially defensive Heatran litterally went TROLOLOLOL at it all day long. Even offensive Volcarona isnt OHKOed by +1 of any of its common moves, and after SR, Volcy has more than a 50% chance to live and KO Gene with STAB Fiery Dance/Fire Blast/Flamethrower
Some of the most common scarfers can blast past even Scarf variants, and slower scarfers, like scarfmence would become more viable, as it outspeeds Scarfsect and OHKOs with Fire Blast.
If you put it in rain, you basically gave it a second weakness (to water) and did like nothing to the fire weakness.
I understand Download was a cray cray ability, but many things could potentially beat Genesect.
