I wanted to say thanks to Oestrus. He has checked my priest spec, glyphs, logs, etc. And while I haven't followed all of the pointers, his advice did make me take a long hard look at my spec and glyphs and take a second look at choices that I had made at some points.
Our raid finally got the Nef kill, after 130 or so wipes and it took a lot of adjusting and a lot of fiddling with things. I'm still hoping for upgrades, but hey...soon.
Anyways, thanks again Oestrus :)
