We have finally started getting into the 3rd phase on LK with our 10 man group. The issue I'm having is mana. I'm running the cookie cutter Arcane spec with the T10 Set with the ICC Crafted legs. I evocate whenever I can. The only way I've found to help with this is buy swapping out the molten armor glyph for mana gem glyph, using Mage Armor, and Flask of mojo. Obviously this is a DPS loss for me. I keep thiking there is something I'm not doing correctly with the rotation that is causing the mana issues. Any suggestions are appreciated.
