24man loot has become completely irrelevant apart from glamour since we got augmentations for crafted gear.

This has started in 4.3 and will likely continue - basically you can have a full set of gear equivalent in ilvl to what 24man gives you on day one of an odd-numbered patch (equal to tomestone, 10 behind augmented tomestone/raid)

About the only thing relevant from 24man is the weekly token for gear upgrades ... so if they really want to do something about people not giving a single care about 24man, let them fix what it drops before they fix how it drops.
