uh, wut?
Weather isn't a single playstyle though. It's at least 4, with at least one being associated with each weather. If we only have weather teams, there's still a wide range of viable playstyles within the weather teams themselves. It's hardly stagnation of the metagame.It's just that outside of a very, very limited amount of things, nothing can contain weather very well so that it ISN'T broken. Weather...hits each other. Non-weather teams...caught in between the weather wars. And many are relying on a single pokemon (who is potentially 1-2 or 3 hit koed by them) to counter multiple things that doesn't have much Recovery besides Leftovers and maybe Leech Seed although when they pound you, it doesn't help that much.
Skarm does the same thing as Nattorei? Since when? And when you throw Scizor into the mix, it has a completely different role altogether.To stop Rain, it invests max hp/max sdef (right? But in any case it still needs a heck of a lot). This takes from defense and makes it eat dirt from sand since a boosted Earthquake deals a lot. It's not likely to run multiple defensive steels on the same team like Skarmory/Nattorei being that they share the same weakness and do much the same things.
Uh, what gets STAB EQ on a rain team?The difference is in the defenses could turn a 3 hit ko (with more defense) into a 2 hit ko Stab Earthquake against Nattorei, which when doubled by Swords is a ohko. It can't defend from both sides THAT effectively as some people make it out to be. And if you go all out for rain, it's vulnerable to sand and vice versa.
Sun's even less of a threat than rain though. And obviously, you don't switch in Heatran on the few sun abusers with access to those moves.It is murdered by Sun obviously. Heatran which could work gets killed by Jump Kicks and Hammer Arms if they see it. Hidiharuma is by the way faster than Heatran so if it's carrying Life Orb (it loses the guaranteed 2 hit ko on Suicune but if Heatran becomes an issue then it's worth it since Flare Blitz is Encourage Boosted without additional Life Orb) it will die. Normal things like Sazandora Scarf are vulnerable to other things
(Mebjuka, +2 Life Orb Venasaur, Scarf Solar Power Charizard, etc) but they will probably lose something to Draco Meteor (unless it's Forretress). Still Hidiharuma and others come in to finish it off.
Uh, you should obviously know how effective the counters to a certain tactic are before banning something. >_>The closest thing mentioned was Lickilicky, Trick Room, and maybe Choice Scarf Golduck? (Ugh, weak thing but fortunately most weathers are somewhat defensively weak but that thing would have problems. Lickilicky is still way better.) But those are only temporary and who knows how actually effective those are (Trick Room isn't really seen much now as it is when it is the best time for it. What would suddenly make it jump everywhere later?)
