What this list is
Gruul's Lair is a 25-player raid, and this page lists 19 gear drops across 2 bosses. It is not the loot table. It is every GEAR item the simulator's own item database records as dropping from each boss — tokens, patterns and quest items are not gear and are not here, and a drop the database never recorded is not here either.
The "best-in-slot for" column is the other half of the page: 23 specs have a published list that picks something out of Gruul's Lair in some phase, and each chip names the spec and the phases. A row that says no published list picks it is not saying the item is bad — it is saying wowtbc.gg's lists, which are the lists every audit on this site grades against, do not choose it for any of the 27 specs.
Trash blocks are listed where the database records a zone drop with no boss behind it. Item levels are the database's. Every item name opens Wowhead, and the raid gear checker will tell you which of these a raider is already wearing.
