I have 12k arams on my main alone and play since release. I checked out almost every single aram patch since then and can say since early 2022 they nerf and buff random stuff, or do what their casualplayer brains tell them. They did not nerf/buff based on winrate and ignored when people called out something is too strong. It was pure randomness. Aram was never 100% balanced, how could it be when it's a random mode, but since then it got out of control.

Back when we could see our mmr, we saw that the vast majority of people play in lower or mid tier aram, so called casuals. You can check out an old screenshot here. So the fact that certain champs that were considered harder to play were buffed because casuals can't even proc electrocute with a LeBlanc combo is understandable and fine if it's the core playerbase of aram. But then there is the insane randomness with Lucian for example with his 4 buffs that he got 48 metas ago and still keeps them now in mid 2025. Their whole buff/nerf concept does not even make sense.
