And hey, I never said that Hail is good. But I do think to giving it more than it has already, will make it unbalanced. True, Hail teams aren't very great, but I can't truly judge those because I never witnessed them fully due to my team. The aggressive weathers are however, very strong due to the fact that if your pokemon is vulnerable to the effect it will:
-make it unable for use of Sturdy and Focus Sash if you don't have something that heals
-finish off a pokemon that has hung on Sturdy or focus sash.
And Hail can affect almost every pokemon with Sturdy in existence so far I think. So do not say it's useless. You're very ignorant.
