Now? Vmaxes always had attacks ranging from "meh" to pretty amazing. Even from Sword and Shield 1, Snorlax Vmax has a pretty powerful attack, it's just that the card pool in standard doesn't support the card. Inteleon has good attacks, Dragapult has a good attack, Centiskorch, Eternatus, Alcremie, etc. Like you pointed out yourself, what makes the card bonkers is its ability, or better yet, let's say the whole package, it does look pretty good, no one is gonna be crazy and deny that. But your second paragraph just isn't true.
The game's not broken in any way. In fact, after Battle Styles dropped, it is the healthiest it's been for quite some time, the meta is diverse, dynamic and fun (this last one is subjective, the other two, are not). It is pretty obvious at this point that, no, Creatures are not a bunch of clueless idiots, even though it might seem that way from time to time, but that happens to every card game. And since you mentioned Magic, as someone who plays both, no, Pokémon hasn't even come close to the levels of stupidity Magic's R&D has, I mean, it's not even funny how much worse Magic has been in the last 2 years. Finally the sets are starting to show a downturn in powerlevel (since they make sets years in advance, it takes a while for them to correct bad trends in game design), but they made some egregious mistakes. Pokémon hasn't done anything near as bad. Pokémon doesn't have any card that is as single-handedly broken as Oko was, to use the most extreme example.
You can say that something like ADP is a problem, but it's not even close to that level of brokenness, unless you underestimate how bad Oko was, or overestimate how bad ADP is. Since we don't have anything near as problematic in the card department, we are left we a more wide and complex situation, where the game state is much more defined by the cardpool as a whole, what support for what types is available, etc. It may seem obvious at first that Vmaxes were destined to break the game even more, I mean "3 prizers with that much more health and that much stronger attacks"? Anyone who looked at that in a vacuum would bet their asses no good could ever come of those cards, right? But look at where we are now, one of the most fun standard eviroments we've had in a while. Turns out, as always, context matters too much, and we just aren't able to fully predict what will be of a given format until sets actually hit, until cards start being played. I mean, anyone looking at the spoiled Urshifus a while back could swear the game would be done, I mean, "card's broken, omgggg", and again...best format in recent times... Let's not get ahead of ourselves, let's wait for the set to drop, and judge how good or bad things turn out to be then.
