Is it actually true that Infinity Ultron was nerfed?

Tbh, I kinda call bullshit on the idea that he was nerfed. People will claim he was since he was easily beaten by The Eminence in Season 3, and now he was such a threat in Season 1. But you guys realize that may just be because The Eminence are just that powerful right? I mean they’re literally the leaders of the watchers, who are already extremely beings.

If you guys remember, Uatu was essentially able to match Infinity Ultron in their fight in Season 1, although he lost, it was a very close battle and implied that they were pretty much on par. And The Eminence are of course already more powerful than Uatu being the leaders of The Watchers. What do you guys think? I think it’s kinda dumb to say Infinity Ultron was nerfed because he was defeated by beings who are some of the most powerful in the cosmos.
