Taking all advice! I have done 6/7 Mage Towers but cannot get past this one. I do have the DBM Challenges addon and have also tried the build from wowhead for MT. I can sometimes get to phase 2 but then run out of room on the floor.
Please drop some sage advice and/or link your amazing spec for p1 and p2. I can change specs between bosses if needed (sometimes requires shadow meld but hey). Thanks in Advance!
