Weak Aura #1
Tracks maelstrom and provides a next ability rotation. Uses timers to track our new pandemic ability by tracking our weapons enhanced buffs to ensure they are always maximized rather then wasted.

Weak Aura #2
This as well tracks our weapon enhancements but instead of just coming up as the next spell to cast we can preemptively plan for when they are coming up. The enhancement required will start to bounce up and down when you are in your pandemic drop off. This is just good for one if you tunnel and forget where you are at in your rotation. Or when you are trying to maximize AoE since the WA above focuses more on single target rotation.

For gear I have only changed my trinkets. I have went with Wordups (huge enhance theorycrafter) suggestion and moved towards the Stone of the Elements and Heirloom trinket (Infallible Tracking Charm). I am not buying the skull of war for 60k at this point. Its just not worth the slight dmg increase.

I have ran multiple mythic dungeons and have found great success with this setup. Come raid day that might change but at this point I am trying to be careful and not compare myself to other classes. Enhancement feels super good tight now and I look forward to Doomhammer.
PS make sure you check out icy veins as wordup has updated and explained all the changes with enhancement for the pre patch. Good luck and may the elements be with you.
Edit: I do not take any credit for these WeakAuras as they are not my own and belong to the people in the links.
