Do Not Ban
Nidoqueen is without any doubt the best Pokemon in the RU tier, but in my opinion it is not broken in the current metagame.
The first thing is that you are not required to use Nidoqueen to have a successful team, many people have proved this on ladder and important tournament matches. This of course doesn't mean Nidoqueen is bad or anything like that, it just means Nidoqueen is not the kind of Pokemon you can mindlessly put in your team and watch it wreck.
Just like every Pokemon it needs team support to work properly and play around its counters and checks. Yes Nidoqueen does have counters, they are not many but they exist and they are perfectly viable in the RU tier. Clefable, Uxie, Gardevoir, Lickilicky, Musharna, and Misdreavus (With investment in its SDef) can switch into virtually any Nidoqueen and beat it without any issue, I'm probably missing some Pokemon because these are just the ones I can remember right now. There are other Pokemon like Mesprit, Cryogonal, specially defensive Slowking and Piloswine that can easily check Nidoqueen in nearly every possible scenario, they are not foolproof counters but they can deal with Nidoqueen most of the time.
Fitting any of those Pokemon in a stall is perfectly possible and they all do a lot more than just beating Nidoqueen. Granted this doesn't mean dealing with it is easy for stall, because it's not. Nidoqueen’s resistance to Stealth Rock and Immunity to Toxic damage means wearing it down with passive damage is incredibly hard if you are lacking Spikes. However most defensive Pokemon have a way of damaging Nidoqueen, which means it can't just freely switch without dying in a match against a stall team.
So if it is possible for stall to beat Nidoqueen, why is stall not as viable as offense? In my opinion this is because there is an absurd amount of viable offensive threats, even some Pokemon in NU are amazing offensive threats in RU like Braviary and Fraxure, and it's simply not possible to cover everything with just 6 Pokemon. Nidoqueen might contribute to how difficult is to build a successful stall team but it just one of the many Pokemon that do that, banning it won't fix anything.
And to finish this post I just want to say something everyone knows, Nidoqueen has problems with offensive and (some) balanced teams because of its exploitable weakness and lackluster speed. It is not dead weight against those playstyles but it is significantly less threatening.
