You can bet my first time doing every new dungeon in DT I'm going to wall to wall because I know the design team is too lazy or cowardly to change any of this, and I'm going to be fine because the tanks are all going to have further upgrades to their level 82 Bloodwhetting cooldowns, everyone's going to be running around in full raid gear and Manderville Relics, and it'll be a miracle if they ever include monsters with mechanics like Final Sting, Dragon/Ram's Voice, midbusters or unavoidable non-tank damage ever again.
