Reposting a slightly edited version of something I said in council discussion. These, I think, are the 3 central factors to why Salamencite must be banned. These arguments are made in comparison to Kangaskhanite, the closest thing Dubs has ever had to broken.
1) Mence has too much control over its own speed, making stopping it more difficult than any other threat. It has a considerably higher base speed than Mega Kangaskhan does, and has redefined what "fast" is in Doubles. Latios and the musketeers are now SLOW. Yeah. 108 and 110 are now slow. WTF. Oh and Mence easily boosts its own speed with Dragon Dance. And Mence at +1 easily outruns tons of things at +2, including all the Base 70s, so Tailwind isn't even the most reliable thing, and yes 70s at +2 also includes Ludicolo and Swampert under Rain. Yeah it's more vulnerable to Trick Room than Kanga, but to say that Mence is more vulnerable to speed control overall, as some have said, is ridiculous. Moreover, Mence can even afford to run Sub or Protect, which protect it from many forms of speed control, most notably Thunder Wave (and also help stall those nasty TR turns).
2) Mence's defensive typing is a massive ADVANTAGE. Its many (five more than Kanga) resistances and immunities along with its bulk and pre-Mega Intimidate make setting up Dragon Dances incredibly easy against a large part of the metagame. Yeah it sucks that it has three more weaknesses than Kanga does, but Jirachi or Amoonguss can easily redirect a lot of those attacks, and Aegislash et al can Wide Guard Hyper Voices. Like any other good attacker, you're gonna support it, and Mence happens to work exceedingly well with many already good supporters in Dubs.
3) Flying resists may be relatively common, but Mence can get around almost any of them by using Dragon Claw (for non-grounded electrics) or Earthquake (for grounded electrics, rocks, and steels), and even if you run a monoattacker, like I have been, most are very easy to play around with redirection. Moreover, unless you always have those specific mons out, Mence is almost guaranteed to get a Dragon Dance off, at which point those checks are very tough to switch in. They're more revenge killers than anything, and not even the most reliable ones on earth. Also, several resistances, such as Heatran aren't checks unless you're running a special set - standard Heatran is just free Dragon Dances for Mence. And the need for Flying-resistances is definitely impacting Dubs. It's become harder to run Steels that don't resist Flying, such as Ferrothorn and Escavalier, because you want your Steel type(s) to be able to stop not only Fairies and Mega Kangaskhan, but also Mence. And that's a real shame, since mons like Ferrothorn and Escavalier are two of the best options against another top threat, Mega Diancie.
