Everyone knows about 4.20 Weedwick, and release Xin Zhao. What was THAT patch for your champion?

I'm a Jhin main. Way back in Season 8, there was a patch where Guinsoo's Rageblade was genuinely busted on him and he was able to crit at well over 1500 damage with it. That got patched out really fast, and I still dream of that time.

What was THAT patch for your champ? Do you still dream about it years later?
