Slowdog's BDK v5 | Midnight 12.0.7 | Deathbringer M+ Tank Macro

Overview Slowdog's BDK v5 is a Blood Death Knight tank macro for Mythic+ at level 90 built entirely around the Deathbringer hero talent tree on patch 12.0.7, and it's the first BDK sequence I've put out that actually runs the Deathbringer engine correctly from the ground up rather than bolting Reaper's Mark onto an existing rotation and calling it done. What it does Reaper's Mark and Dancing Rune Weapon sit at the top of the loop so they fire the instant they come off cooldown without waiting for the cycle to finish, and that matters because losing even a few seconds of DRW uptime across a full key adds up fast. Marrowrend runs twice per cycle to keep Bone Shield healthy and consume Exterminate procs through Painful Death, Death Strike fires once per cycle as the primary self-heal with an emergency cast sitting on Shift any time you need it, and Blood Boil gets three passes per cycle to prevent charge capping and keep Reaper's Mark stacks building through Bind in Darkness. Modifiers Shift is Death Strike on demand. Ctrl is Vampiric Blood -- time it to incoming damage rather than letting it fire passively. What's not in it Death Grip, Gorefiend's Grasp, Anti-Magic Shell, Icebound Fortitude, and any grip utilities are all manual and should be bound separately. Setup Import the GRIP string via /gems import, load the talent string in the Talents panel, drag it to your bar, and bind it. Bind all your manual cooldowns before you pull anything. Press Shift before you need it, not after you're already in critical mode. Validation Tested at 257 ilvl on patch 12.0.7. Timed a +10 Maisara Caverns with Blood Plague uptime at 98.84%, Dancing Rune Weapon uptime at 97.47%, and Reaper's Mark and Exterminate counts aligned throughout the key.
