As for the DP glyph: I wouldn't glyph it. In P2 and P3, there are more than enough nature damage going out to justify it. Especially in P3, with the stacking debuff, which is one of the most damage-heavy phases. It might also help with soaking Static Shock.

^both works nicely, FW/AS depending on you. FW again helps with the last burn-phase. And FS depends on how fast the adds die. If they are a problem then don't use it, and maybe glyph Holy Wrath for the stun.
