Also, to clarify, there are still some equally ridiculous claims on the other side of things, stuff like "irelia never should have been printed". Personally, I'm glad that we have a new archetype that plays really uniquely, and that it uses ionia and shurima, two regions that were kind of struggling with their identity before. Is it too strong? Oh absolutely.
The thing is, and this is I guess a hot take, but I'd really rather they print new stuff "too strong", rather than "too weak", especially when that new stuff is able to bring to life a new playstyle to figure out. When Lee Sin archetype got a total of like 5 buffs across 2 balance patches, sure he was super OP but I was very happy with this bolder stance on balance; an opinion which people were pretty outraged at hearing at the time because, well, he was super OP for a bit. But I think bold balancing and having to deal with a strong new deck for a few weeks is worth being able to have a new unique and viable archetype forever.
And to be perfectly frank I think that most of the balancing the devs have done has been extremely softhanded; usually just tiiiny buffs over a long period of time that will maybe eventually make a real difference in like a year. Look at Lulu and Vlad's archetypes for this; Vlad's tiny incremental buffs were able to make him feel viable but only over the course of about 15 months, and at this rate Lulu will need about 6 more.
In fact one of the pieces of feedback I personally gave to the devs last year is that it feels like their internal playtesting team is almost "too thorough" (in more cases than not, there are exceptions for sure), but there have been a lot of cards that have felt like they could have been interesting if they had come in a little hotter. A LOT of the super scaleable combo pieces (that normally in card games have the ability to do crazy things) feel overbalanced and kind of watered down by the time they get to us. Think Arrel the Tracker and stuff.
So, while it's important to acknowledge that it's absolutely an OP deck, I also don't think that's a problem per se. It's definitely not ideal, but the actual problems are the cards that are getting printed too weak as opposed to too strong. We should be talking instead about Malphite and Zilean. :)
