What glyphs should I be using?

Moonfire and Starfire glyphs for raiding are essentially a must. They synergize so well with each other. MF and SF will still be primary spells used in any rotation (even for those of you that spec loleclipse) and with SF adding duration to MF (note ADDING duration, not refreshing it), the initial damage from moonfire becomes a moot point, so adding to the periodic damage will only benefit you, hence the MF glyph.

The third glyph should be Insect Swarm. Insect Swarm got a huge buff in damage with 3.1 and adding 30% more to it will only help your dps

As far as minor glyphs go, there’s no glyphs that will increase your dps currently in the game, so really these are all personal choice. Myself, I use the glyph of Unburdened Rebirth, Glyph of Dash and Glyph of the Wild.
