Not being the highest in the statistics doesn't necessarily mean a Pokemon is broken. Deoxys-S and Wobb, the two Pokemon considered the most broken Pokemon to have ever been tested in OU, never reached the number one position. Wobb didn't even make it into the top ten. Saying that a Pokemon doesn't deserve a test because it isn't the most used isn't a valid argument.
Another argument for Salamence not needing a test, that Stealth Rock makes Salamence not broken, annoys me just as much. It's definitely possible to prevent your opponent from getting SR up in most situations. Scarf Breloom is faster than all the common leads other than Aerodactyl and Scarf Jirachi, and can put the opposing Pokemon to sleep on the first turn. Lum Berries aren't especially common on leads anymore, so most of the time, Scarf Breloom prevents the opponent from getting up Stealth Rock, or at least delays it. Aerodactyl can do the same thing with Taunt, and has the bonus of Taunt not being affected by Lum Berries. So it's possible to build your team to avoid having Stealth Rock laid on your side.
Without Stealth Rock up, Salamence becomes much more threatening, to the point of being Uber. All the Pokemon mentioned earlier as Mence checks can just be switched out of with minimal cost. This is especially true for Mixmence, because you get to immediately do damage on your free turn and not potentially waste a turn setting up a Dragon Dance when you'll have to switch out. When there is no SR on the Salamence user's side of the field, one misprediction from the defender can cost them one key Pokemon or more. But if the Mence user mispredicts, the cost is much less, because Salamence can be switched back in later and not take entry hazard damage in the process.
With all the controversy in this thread about whether Salamence fits the offensive characteristic, the best solution would be to conduct a Suspect Test for Salamence to determine who is right. The issue would not be settled definitively if Salamence were not tested.
