I might sound off topic here for a moment, but bear with me, I have a point. I still think it's bullcrap that Garchomp was ever taken out of OU. I know all the arguments that you are preparing to throw at me right now, the stealth rock resistance, the fact that his speed is higher than Salamence's (more on that later), and his higher bulk than salamence's.
I'm going to stick with my Garchomp rant for a while, because much of this also relates to Salamence.
People often complain(ed) about Garchomp being fast, here's the simple argument to that. No he isn't. Without a way to boost his speed, he's dead in the water from a Starmie's ice beam, a Weavile's ice punch, a Gengar's Ice Beam, a DD'd Gyrados's outrage, a Jolteon's HP ice, a Scarfed Flygon's outrage, a motor drived electivire's ice punch, and that's just what I could think of off the top of my head, not including priority moves.
With a scarf, he had no versatility and, no matter which way you slice it, base 130 attack still isn't enough to pull off a sweep without some sort of boost. (and before you say it, base 135 isn't either).
Salamence is infinitely better than Garchomp for that access to dragon dance, but that doesn't make him the god that many claim he is in the OU environment. He still has the weakness to ice shard, and an additional weakness to Stone Edge, which can be critical.
Salamence has so many weaknesses, from the ice that most special sweepers carry to the stone edge that most physical ones do, that anything that survives his attack (there are a lot more than are being listed here, hell, this even includes an ice beam blissey) can have a good shot at killing him. Couple that with Life Orb, and Salamence has very little potential to sweep a team that hasn't first been significantly weakened and cleared of his counters.
I often think the concept of an evolving metagame is somewhat funny, yes, i get it that when certain pokemon get new toys (I.E. Iron Head for Jirachi or Bullet Punch for Scizor) it can change the game a bit, but dragon dance TTar is still as great as he ever was,despite having somewhat fallen out of style, same with a Bold Blissey, the game often changes for arbitrary reasons, while Salamence has changed very little, countering many new pokemon that come into style, the game has changed around him.
Salamence isn't "too good" for the metagame, the evolution of that metagame led straight into a wall, and that wall is Salamence. Now Smogon asks you a question, is it appropriate to allow the game to continue to evolve by forcibly making the evolution continue? Or do we accept that just like a bullet punch Scizor or a Dragon Dance Gyrados, Salamence is a powerful, but integral, part of the game?
Let's not make the same mistake that was made with Garchomp here.
Just for grins, I'll give you three reasons that Salamence should stay around, his counters still exist, but people just don't think of them. These are
1) They don't build Blisseys like they used to. Used to be that Blissey could survive anything short of a DD+LO outrage, now people complain about salamence because she can scarcely survive his earthquake. For some arbitrary reason, people decided that Blissey needed to lose much of its physical defence. Losing your walling ability against salamence is the price you pay. I don't care what people say, Salamence is really not that bulky, he can't even survive an ice beam from blissey.
Bold Blissey never stopped being good, it was just randomly decided that it should be able to survive Gengar's Focus Blasts, when Blissey really has no business staying in on a Gengar in the first place, and the whole Smogon community followed like sheep.
2) Weavile. I'll tell you what happened to this, Bullet Punch happened. Without being first intimidated, Weavile crushes salamence with ice shard. Even if he has taken an intimidate, ice punch can still hit the weak point for massive damage, given that Walamence hasn't had the time to set up if Weavile takes the intimidate.
3) Starmie. I really can't tell you what happened to the offensive Starmie. It has great speed and good enough special attack when combined with it's superb type coverage. I guess the rise of TTar hurt it, but I really don't know. Anyway, two words. Ice beam.
None of those three counters even need a boost to OHKO Salamence, and none of them are specifically designed to take him out, and have their own niches in the metagame. (side note, all three of them counter Garchomp beautifully, his removal from OU is still in my opinion the worst decision Smogon ever made)
