The OLT is great for practicing, since I'm getting matches aganist insane players like Leng Loi or Kebab in my "Low" elo (1750s- 1800s). I'm having a great time on the ladder this week.
However, while this is very cool and I'm learning a lot, I gotta say I'm getting extremely tired of one Pokémon:

.
Dragonite has no business in this tier and it's the most annoying Pokémon to face in OU. It has 600 different DD sets (included, but not limited to: Tera Blast of the Tera type, Ice Spinner, Fire Punch, Scale Shot, Extreme Speed, Earthquake, Encore, Roost, Low Kick, Rock Slide, Dragon Tail...) both boots, leftovers, sharp beak and Loaded Dice each one not having exactly overlapping checks except extremely passive stuff like Dondozo, even less if you account for tera.
It can also go HDB utility with Dragon Tail and Banded. Again, those sets have different answers and sometimes have different checks, that are really different depending of the coverage Dnite has.
And I'm strictly talking about viable and usually used sets on the ladder. I'm not talking about niche options like special on rain or the bulky one with Twave used Lax used on tournament (yet I could actually add that last one to the tier, I won't).
It also has so many tera variants (included, but not limited to: Normal, Flying, Ground, Fairy, Ghost and Fire). I can understand a Pokémon having one, or two different tera types, but
SIX? Some of them beaten by Zamazenta or Gambit but others just using it as set up? It's extremely toxic and cheesy.
Volcarona, Roaring Moon and Gouging Fire had less sets, were most of the times far riskier since they don't have multiscale, and did not have access to priority or Encore. The three of the do share recovery moves tho.
I think that facing Dragonite it's extremely annoying and that using it feels cheapier than a 99 cent store. This Pokémon has to go sooner than later in my honest opinion.
