Who said that? It's 100% in the rain, 70% in any other weather.I wasn't refering to the Accuracy. I was refering to the fact that Gale doesn't work in anything else other than rain.
Btw, Gengar is using Focus Blast as a coverage move to use in tandem with his STAB Shadow Ball. Gale would be Dragonite's main STAB, and considering its accuracy, that's not reliable at all. Having to hit Tyranitar one time in a battle is different than spamming a 70% accurate move.
