I get why people are upset but this same thing happens in any game where a handful of builds or items get overused, the dev almost always nerfs them to hell to get under utilized skills, builds, and items used.
Havent read the full notes yet but increases in renown for side quests and dungeons being retroactively applied is a good thing and them nerfing freezing monsters from being able to 1 hit freeze continuously until death is also welcome.
They nerfed everythin though. the same good builds will be the ones used, they'll just be weaker.
Just an objectively trash ass patch.
