I think it's kinda unfair even considering getting rid of weather. Weather is another way of play, you use it or you don't, if you don't and you find yourself coming across more, then have a counter. It's like (but not the same) as every other big thing that comes with a new metagame. Last gen we had Heatran and Scizor, and they. Tore. Shit. Up. But people would throw in Magnezone for counters sake and the like.
Weather, sure, rain is the most broken out of the lot, working with Swift Swimmers, Hydration Vaporeon and 100% acc. Thunder and increased Water-power, weaker Fire, but with Politoed banned with Swift Swimmers (which I'm against) you still have to spend a turn to set up rain for a Swift Swim team.
Sun is cool, but doesn't offer as much, increased Fire-power, weaker Water and 1-turn SolarBeam. This used to be a gimmick, and frankly still kinda is, we just have more who can use the sun.
And sand. The bitch of last gen. The reason we ran Leftovers on nearly everything and their Mother. Does damage, increases Rock Sp.Def by 50%, and allows Garchomp to hax out and evade a move or two.
Finally, Hail. 100% Blizzard, and damage each turn. The worst of them IMO. Abomasnow is rarely used, but when it is I can't really say its uncounterable, even without prepping for one.
Considering the majority of Smogon wants weather gone, I can kinda see that those players against weather won't be running weather-teams, with perhaps a few exceptions.
The way I see it weather is a play style, much like people like to use Parahax for a team strategy, it's annoying and some consider it a gimmick, but it gets wins, and it loses.
Perma-weather teams aren't really a problem for me, and I'm really confused as to why it is such a big deal. Don't like it, don't use it. Hate seeing it, run a counter, just like we did last gen. Ninetales , Politoed, Tyranitar and Hippowdon and not that broken.
People are having fun with it, so just because some people can't hack a loss to weather they want it gone.
I am not a weather user, and weather is annoyingly good, but we all know its not really broken. Oh Noes Politoed! Yeah, Toed+S.Swim banned. Tyranitar? We dealt with him before. Ninetales? Big whoop we all run EQ, and Stealth Rock is still a bitch to Fires.
Hail? Please.
I'm for perma-weather NOT being banned, because I think it's unfair. It's not hax, never will be.
