There's a new Diablo 4 patch out, and while it addresses a couple of the latent problems in Season 14, the bigger issues surrounding Mythic Uniques remain. Specifically, their drop rate is far too minimal, and crafting them is still not worth the effort.
As usual, players have been quick to see what's been altered in the latest update, and what they've found is disconcerting. Prominent Diablo 4 streamer and YouTuber Rob2628 noted on Twitter that after a quick session beating the newer Reaper Bosss over and over for loot, he got plenty of Mythics, but none of what he's been looking for.
