It's a pretty solid set, I made a couple of tweaks and came up with this. It's a Disc/Shadow talent setup but the gear wouldn't really change for Disc/Holy. I prioritized more mp5/resilience for gems but otherwise we're really similar.
So, I made a lot of changes. In most slots, it's damn hard to beat the boe physician blues (even with epic gems). The link in the first post is now what I'm going to run. It has 700 more hp, 700 more mana, 140 more healing, and 4 more resil than the link in the second post. Any Faerlina Horde groups?
