So what?
Who cares if it's overcentralized. Overcentralization is a terrible reason to nominate anything.
If everyone starts carry's scizor, so what? It's called bring a scizor counter.
If weather is the metagame, so what? It is what it is? The only concern should be if it's broken or not, if it's popular so what, all of a sudden things need to be banned, because people are using it?
It's funny because the tier gets called "overused"/standard, complaining about centralization in something called overused sounds retarded.
Overcentralization isn't a reason to ban things, it just makes you wonder if the reason something is used, is because it's broken.
Why should we care if you can't use a "balanced team", not like much people care if a drizzle ban smashed rain stall.
Far as I understand, your playstyle doesn't matter at all, and the only thing that matters is whether or not something is broken. If your playstyle dies, I believe the phrase, unfortunately is "too bad"?
Who cares if banning Mewtwo stops someones playstyle of using some retarded Mewtwo set that isn't "broken".
Someone can surely correct me If im wrong but when did overcentralization ever matter? Garchomp? Please they gave more reasons than overcentralization.
I don't mean for you to take offense, and I apologize if you do.
Everyone carrying Scizor wasn't Scizor overcentralising. It was
Salamance. As soon as Mance was banned, Scizor's useage plumetted. Scizor was being used so much because of his ability to revenge kill Salamance.
Another example, Latias. Scarftar's useage fell lik a rock after her banning.
Generally, if everyone starts running the same thing, or things to counter said thing, that's a sign something is wrong. There's 300+ fully evolved/viable NFE's now. Yet everyone's running the same tactic, or something that can check *read, not counter* that tactic? That's a VERY strong sign that something is wrong.
Overcentralisation is not nessacerily a sign something is broken, but it sure is a symptom. If something is broken, naturally, everyone will either start abuseing what is broken to win, or specialise their teams to counter the broken factor, leaving them vunerable to others.
I've said it before, and I'll say it again. CAP proved Drizzle [And Drought] to be broken IN THEIR OWN RIGHTS in Generation 4. The only 'nerf' Rain and Sun have recived in this generation is the increased viabilty of sand as an offensive weather. Meanwhile, Sun for a truckload of new abusers, and Rain got new abusers and excellent support options [Nattorei resists all weaknesses of Water-types...]
The existance of Doryuzzu [Which is the only real nerf Rain/Sun have recived in Generation 5] is not enough to make up for all the buffs they have recived. I'd be astounded if Drizzle didn't get a Supermajority this time.
And yes, this will probobly lead to a spiral. Drizzle will be banned, which will leave little to check Doryuzzu. Dory will then probobly be banned. Then, Sun might just wind up banned, due to less sand. But the thing is, we're looking for a balanced metagame. It dosen't matter if there's different 'teirs' of brokeness, of something is to much, and dominates the metagame, it needs to be banned.
Drizzle writes off so many team types, and you HAVE to be running a counter to it to even stand a chance agaist a half-competant player. And, by counter, I mean 'other weather', you can't even check Drizzle teams with pokemon, really, unless you're using Trick Room. If the game's degreading to weather wars, you know something is wrong.
Porygon2 outclasses it at what? Getting set up on? Deoxys-D has Stealth Rock, Spikes, Cosmic Power, Pressure, and Taunt over him. These are moves that support the team and prevent him from getting set up on, neither of which Porygon2 can do well.
Porygon 2 has 105 Sp.Attack. That's more than enough to stop more frail pokemon setting up on him, even if univested. Especially with the rather good coverage P-2 has. P2 and Deyoxys-D play different roles. P-2's better as glue for an offnesive or balance team, Deo-D is better for stall.
