Blizzard has pushed a round of Mythic+ tuning to World of Warcraft's live servers, touching three dungeons in a single late-night pass. Wowhead reports that the changes raise the enemy forces requirement in Blinding Vale while nerfing several of its pulls, soften two of Murder Row's hardest lieutenants, and remove a positioning trick players had been using in Altar of Fangs.
Murder Row
The Warlocks that sit between the second and third bosses have been among the most durable lieutenants in the dungeon, because they can both heal themselves and put up a shield. Wowhead notes they are now slightly less durable: Dark Pact shields for 30% health, down from 35%, and Fingers of Gul'dan targets four players instead of five, though each cast now summons four imps rather than three.
Wowhead also lists health changes on Lithiel Cinderfury, Wild Imp and Furious Vilefiend as possible rather than confirmed, and says the dungeon's final boss appears to have been nerfed as well.
Blinding Vale
Blinding Vale now requires 686 enemy forces to complete, up from 655. That extra 31 count is largely offset by a second hotfix in the same pass: the Potatoad Matriarch now grants 60 count, double the 30 it previously awarded.
The Matriarch was nerfed alongside the count change. Its Toxic Spew now deals 50% less initial damage, and Toadspawn spawn within a 7-yard radius rather than 10. A health reduction on the Matriarch is listed as possible. Wowhead's practical read is that groups who have already pulled the Matriarch probably do not need to rework their route, while groups who have skipped it may now want to include it.
Altar of Fangs
The third change is a fix rather than a tuning pass. Players had recently found that Altar of Fangs' healing absorb could be avoided by breaking line of sight. Blood Sacrifice can no longer be line-of-sighted, closing that option.
Wowhead lists all of the changes as already live.
