Glyph of Haunt *new* - The bonus damage granted by your Haunt spell is increased by an additional 3%.
Glyph of Life Tap *new* - When you use Life Tap, you gain 20% of your spirit as spell power for 20 sec.
These aren't all the new glyphs, just the ones I'm thinking of using. I will be subbing these two in , probably removing Glyph of Immolate and something else. If I get my hands on another piece of the T7.5 set, I will have 50% of my spirit converted into spell power with the glyph and my fel armor with one life tap, not to mention the +300 spirit I will be getting from said 4 piece set.
