Every TBC raid drop, boss by boss
Pick a raid and see every boss's gear drops on one page, or pick one boss to condense to it. Each row is an item the simulator's own database records as dropping there, with the specs whose best-in-slot lists pick it and the phases it is the pick for.
Pick a raid — Karazhan, Gruul's Lair, Magtheridon's Lair, Serpentshrine Cavern, Tempest Keep, Black Temple, Hyjal Summit, Zul'Aman or Sunwell Plateau — then a boss, or leave it on the whole raid; the boss picker's counts are how many gear drops each boss has. Filter by class to keep only the drops some spec of that class wants. It is a loot-driven record rather than a best-in-slot one, so a drop nobody's list picks says exactly that.
