Hope Kyurem and Victini (well near everything) get banned soon.
Kyurem can do so much damage its unreal and essentially forces you to run Registeel because nothing else beats it well at all (Focus Blast nails that nicely though). :\ It can also run insane sets from anything from Specs to Hone Claws Mix sets with Blizzard or 101 HP Sub set to crap on Chansey. In Hail its even more difficult to deal with since it can just click Specs Blizzard. It also runs HP Fire as a standard move ever since people started using Shubarugo/Bug Knight to check it. -_- That and people use Magic Bounce and Spinners with it so even SR is unreliable.
Victini also only needs V-Generate and Fusion Bolt to GG everything. Ive also seen Expert Belt Mix Sets that lure in Suicune with Grass Knot etc ughh. Once again it forces you to have a weather changer so Drought doesn't make it 2hko even 4x Fire resists like Kingdra and Omastar or a Flash Fire user. ._.
Baton Pass and Mew probably need to go to. Those dual screen Mew/Smash Pass teams are frikking stupidly broken.
Either way i hate this metagame, its terrible and retarded because of the arbitrary cut off point, OU is too small. Everything in UU is basically broken as they have few checks/counters. :\ There are no good steels so you can just spam dragons all day and win. You're forced to run a weather counter still just to avoid getting obliterated by drought and hail teams. ~___~
Lastly don't even get me started on Reckless Staraptor... ._.
TL;DR "wow ubers is a more balanced metagame."
TBH I agree with most of your sentiments. Kyurem is hell, really, though I think a much better check than Registeel is Cobalion - it can come in on a Blizzard or Draco Meteor and at the very least force it out by outspeeding and threatening an OHKO with CC. It's the best check to Kyu I can think of, anyway. 101 Sub sets are really what make it broken imo, though - absolutely stuffing everything with its, what, 125/90/90 defenses? + a decent defensive typing with its Dragon-type and then not even Chansey being able to break it is all just ughhh. Kyurem is probably the most broken Pokemon out of any UU mon, imo.
I think Drought in general is broken, though I've only fought one or two effective players. Victreebel on its own really just mashes basically everything, and then that coupled with Victini and other decent Chlorophyll spammers makes Drought really too easy to smash through everything. The only thing that sucks for it is the awfulness of Vulpix which limits its ability to combat with Hail and Rain Dance Kingdra (does that even work lol). It's really really good when played effectively. I don't think Victini will be so powerful once the sun is gone.
Smashpass is broken and annoying as hell, especially with Taunt Mew stopping you from Roaring everything. >:<
Yeah, Dragons are also OP though I guess the only two usable ones are Flygon and Kyurem. Altaria is kinda... awful, and then icr if there even are any more lol. Eviolite Shelgon!? Nahhh. I mean, between running Cobalion and Kingdra, I had both weathers covered more or less with Weavile to pick off weakened Grass-type sun sweepers. I never had too much trouble with weather but I already built my team to deal with those kinds of threats.
Reckless Staraptor is insane. When I saw it at first, I was like "oh hell that must be CB" and then when it outsped my Weavile and OHKOd with CC I realized that it was Scarf. CB Staraptor will demolish like everything. :| I never really had much trouble outside of what you've mentioned, though. :<
