Sorry, I didn't go through that whole thread. But I think you are fooling yourself if you don't see how much of an impact Salamence and Latias has affected the game (I'll ignore Manaphy for now.)
Obviously they have a big impact on the game. They're both top 10 threats. Why does having a big impact on the game make something uber? Scizor has a much bigger impact by itself, but I don't see anyone saying that this pokemon is uber. While it can be said that Steels such as Scizor are only high because of Dragon usage, this would be wrong, because many Steel-type pokemon are just great in general, such as Jirachi, Skarmory, Scizor, Lucario, etc.
This is my experience, Salamence is the best fucking OU dragon. This boy/girl has won me many matches effortlessly. It has consistently gotten me at least one sweep that allowed me break the game open in my favor whether its DD or Mix. It has won me some important tournament matches in which it destroyed teams by killing off at least 2 pokemon and even nailing me late game sweeps without much support.
Really, consistently? With all the Ice attacks running rampant in OU, and even Stone Edge, I find it hard to believe that you can wallbreak/sweep with it consistently. Unless you're ridiculously skilled or something.
Also, the fact that you had to use Salamence lategame in those matches to sweep means that it did require support. Ie. getting rid of its checks/faster scarfers/priority users.
I was never a fan of using Latias, but I have seen ppl use sets like Expert Belt and CMRoar or ReflectRoar so efficiently. But one set I do use a lot is Specs. Its unbelievable how I can break things open with just one click on draco meteor or even surf.
Any hard-hitting Choice user can "break things open" by using their high-powered STAB attack. And like any choice user, if they pick the wrong move, they risk letting the opponent set up or kill the opposing Choice user. Yes, Latias can switch, so what? The opponent isn't going to be spamming Earthquakes or Psychics once they recognize that Specs Latias is on the team. They're going to be more cautious, minimizing the chance that Latias can come back in alive. This is how most Choice users are dealt with, and Latias doesn't seem to break that mold.
Latias/Mence switching places in usage don't shit to me. Deoxys-E was sixth place in AUG 2008 ladder and it was banned. There are times where a team I would use a team with mence exclusively and break shit and use a team with Latias and break shit. Or even both to break even more shit (but I don't really like using it.)
Obvious Latias/Mence switching places in usage does nothing to you. Ever think that perhaps you're more skilled than the average player? Perhaps that's why you can "break shit" with both pokemon so easily. Usage stats look at the whole picture of the metagame in an objective way, not just what you think.
Deoxys-E was in sixth place and was banned because there was 20 voters in that test, and the only people playing, besides a very select few, were playing to get it banned, no other reason. The suspect ladder was pretty much completely dead during that test, and required getting a high rating on two different ladders.
Fuck, you want to know how much impact Latias has gotten. IMO Snorlax is the true counter, but if they fucking bitch latias fuck over my snorlax with a crit, im screwed? Should I add another check to complement Snorlax, maybe, but Snorlax isn't that easy to fit into a team. Oh man, ScarfTar usage rose because of Latias. I didn't need to use ScarfTar because CB was even better, DDTar was more accessible to my teams, and I could still use shit like mixtar and lead tar without worrying about Latias. But its gay that ScarfTar wins 50% of the time vs SpecsLatias. Fuck, I use Scizor to check Lati, I get fucked by hp fire or 2ohkoed by specs after switching in. CB Max Bullet Punch doesn't even do enough to ohko after 1 SR. What happened to those Phy. Def skarms? Oh its gone, because Sp. Def Skarm actually take on Latias better. Yes, Jirachi is one good ass diverse fuck, but its apparent in my teams that mostly I use ScarfJirachi as a check for Mence, Latias, and late revenge kills. Hell, if I want to use CMJirachi, I better look for other options to beat Latias. Aww, now I have to use ScarfTar or the more risky baittar, Scizor, Sp. Def Skarm, Blissey, and fucking cradily?
If you crit the opponent's counter to a certain pokemon and it kills them, of course they're screwed. Latias isn't any different here. This obviously wouldn't require another check; we don't normally put 2nd counters for a pokemon as a backup for a crit of all things, and Latias is no exception.
ScarfTar, as Haunter has stated many times in this thread, is simply a really good pokemon. It didn't rise solely to beat Latias, it's also a guaranteed counter to Rotom-A, a great revenge-killer, absorbs Trick for Stall teams while also being a ridiculously defensive pokemon at the same time, etc. Also, so what is Latias wins 50% of the time against ScarfTar? The Latias user still has to predict perfectly, or else they lose their Latias. If ScarfTar came in on a Trick, Latias is dead no matter what.
Scizor is still a good Latias check, because HP Fire is still rare on Latias, and opens it up to a lot of other threats. It's also not as if people can't use the Specially Defensive versions of Scizor, which are also good for countering stuff like Gengar.
"What happened to those Phy. Def Skarms?" They were fazed out because Specially Defensive Skarm is just plain better, not because of Latias. A lot of Skarms resistances are specially-based, and people realized that maybe it shouldn't be getting 2HKOed by stuff it resists. Also, it lets Skarm set up Spikes against a wider variety of foes.
CM Wish Jirachi still beats Latias, especially non-CM ones.
And as for your last statement, obviously not. It's also not as if any of those pokemon are bad pokemon either.
Why wasn't Latias a problem before? Because we didn't have as much experience as we do now after finding out hey: Specs is good, Expert Belt is good, LO is good, it is an amazing supporter, and CM set isn't really the best set after all.
Yes, and with that experience we've gathered over the past year, people have adapted to it.
I played since 2006 man and never in life has my teambuilding been limited since Garchomp era. Fucking how did latias open up my teambuilding options? It opened my options because now i can use latias? And now because since Latias was introduced that it evolved game, I can finally use other options to deal with it and fucking ubermence (don't wanna get into it)?
No, it opens teambuilding options because it makes all styles of play more viable because it can fit on each of the team styles.
I didn't complain much when Latias was OU and yes I evolved my game to deal with it. Shit, my glory time is even when Latias is OU when I created the most unique and successful team I have ever built in my life. But overtime the game has become so centralized, my teambuilding options are limited. I can't even get out of standards anymore. We all know people evolve as well and become more familar with the game.
First of all, I don't know how many more times we're going to have to say this, but
"centralization does not necessitate uber status". Also, if you can't get out of standards anymore, then stop trying to counter everything with your team. Although I don't know anything about your teambuilding skill, people tend to only use standards because they're trying to deal with every single threat, but as DPP has shown us, this simply isn't possible with only six pokemon.
