looked a bit at hellfire high council:
-You juggle A LOT with SEF. Why is that? Is it for your guild's strategy that you need to cancel SEF/reapply it several times?
-You start the fight 5 seconds in. It cannot be allowed that you take this long to set up SEF. Conjugate, one of the very best mechanical windwalkers out there, who we all trust with everything, doesn't use SEF on dia in his first TEB rotation because she's slow to come down, then casts SEF with an @
mouseover macro from is raid UI. This goes a long way in saying that this IS an actual concern, and that you should worry about it, but wasting 5 seconds running is NOT the solution.
-You use mirror of the blademaster 15 seconds in, completely missing out on ring. That kind of stuff is baseline too and you have to fix it for yourself before asking for advice, you're smart enough to see why delaying first mirror till after ring is gonna mean you'll miss out on each ring cast with it.
-Overall, your mirrors of the blademaster are extremely delayed. That's very bad since not only does it mean they don't line up with ring, but also you miss out on some casts. If you're unconfortable with it, either make a weakaura big enough for it, or use malicious censer or something else instead.
