I'd say that when it comes to spectrier people are getting too focused on the fact that spectrier can beat any of its' counters and forget that to beat its' counters spectrier needs to sacrifice the ability to fight other counters or forms of counterplay. for example, to counter blissey, it absolutely needs CM, disable and a non ghost attacking move.Thats 3 moves that it's not running because it wants to(if it could get away with it, it would prefer nasty plot to CM, coverage to disable and not to be forced to forgo either a STAB attack or substitute), and it heavily reduces its' general power. Also, people forget that you can counterplay it as a team. Take for example that set that counters blissey. Does it still counter it if toxic spikes are up? hell no it dies before being able to CM. This is where you would say "but then you need 2 pokemon to take care of one"; but can you honestly say that you are using blissey, the best all around special wall in the tier, JUST to take care of spectrier? Or that you are using toxic spikes just to counter spectrier? In general I'd say people expect to just take care of an opposing pokemon by sending in one of your dudes that counters it, but I'd say it's kinda nice to have to use combinations of moves and pokemon to handle different things, if those moves and pokemon can do other useful things outside of countering that pokemon.
Also it kinda needs to be said, sometimes spectrier will just clean house. It's a cleaner pokemon, it wouldnt suck if it couldn't do it. it can absolutely kill like 4-5 pokemon in a sweep and that's what you will remember, and not how your opponent got to this situation by chipping your resist, killing your special wall and checking for scarfers on your team as well as possibly keeping the field clear of tspikes,screens and other stuff that heavily hinders it.
That said, I do think the pokemon is very powerful and absolutely capable of some ridiculous feats, and that there is exists some variant of it that 6-0s any or almost any team, but for every variant that does that to your specific team, there are like 5 variants that don't, and can indeed feel very weak against what you specifically are running (like any choice set against ttar or blissey, or hell even urshifu or something like that). It's like everyone has that one traumatic experience with it that makes them imagine a monster spectrier coming in out of the gate with +1 spattack, a sub and 6 moveslots every game, and that is coloring their perception of it.
I will say that I'm writing this not as a way to say spectrier is weak or something, it's obviously not, but just as a person that doesn't like the idea of prematurely banning stuff, and instead leaving time to try to adapt to it, and only using bans as a far off last resort to things, and I might also be playing a bit of the devil's advocate here, which I like doing whenever people are starting to put attention to potential problems to offer a bit of a counterpoint, just for due consideration.

KO'd by Flare Blitz /U-turn momentum if they run away
Predict the switch and quake it
252+ Atk Darmanitan Earthquake vs. 252 HP / 252+ Def Toxapex: 136-160 (44.7 - 52.6%) -- guaranteed 2HKO after Stealth Rock
252+ Atk Sheer Force Darmanitan Flare Blitz vs. 0 HP / 0 Def Nidoking: 366-432 (120.7 - 142.5%) -- guaranteed OHKO
252+ Atk Sheer Force Darmanitan Flare Blitz vs. 0 HP / 4 Def Spectrier: 444-523 (130.2 - 153.3%) -- guaranteed OHKO
KO by quake / U-turn momentum if it runs away/ U-turn high damage if Suckerpunch
Even after one speed boost is still slower and gets KO'd by quake
252+ Atk Sheer Force Darmanitan Flare Blitz vs. 244 HP / 0 Def Melmetal: 434-512 (91.9 - 108.4%) -- 87.5% chance to OHKO after Stealth Rock

. Sure you gotta run away (not turn) from every Lando-T but that's a fair price and your team should be ready for Lando-T anyway. 
) after seeing someone mention it earlier in this thread and it's really good. Ice/Ground is nearly perfect neutral coverage as shown with Mamoswine, and Freeze Dry just makes it better.
and complex bans in general. I know this is a can of worms, but I do think it merits some more discussion, even after so long.
and the other mons this combo is used with, like 
in SM OU. I don't think any person in the top 500 or even 1000 thought seriously that Lando-T needs to be banned.
