Sapphire of Defense +16 scaling to +32 is pretty damned sweet. Much easier for light armor toons to hit the 100 MRR cap now, without having to slot Magical Sheltering.
Also, +19 skill diamonds are useful. Heal and Spellcraft come to mind.
The ML24 Insightful stat augments didn't change though...? They are still +2 Insightful stat. According to Cannith Crafting, they should be +5 at level 24.
