Another thing to point out, if he is sticking with the T12 4pc he should have Lava Burst Glyph over Lightning Bolt, this is a big mistake. Lava Burst Glyph > Lightning Bolt.
As for the DPS on Ultraxion, he does not pre-pot, nor does he pot during the fight which is lowering his DPS. Unleash elements should never be used, nor should chain lightning used on a single target fight.
Reckless orange gems (+20 int, +20 haste) should be Adept (+20 int, +20 mastery).
I hope this helps, there's a lot this guy could work on.
