A couple things that might help TC. You're losing Thunder up time for a few seconds with Thunder 1. In your video it was down about 4 to 5 seconds. Try Thunder 2 instead. Another thing, if you have a Firestarter proc while in UI, use transpose to go into AF1, then use your proc. I also use HQ poison pots and HQ Intelligence pots to give my dps a boost in T8. You can try that.
