Sucks, but that's how it is.
Wrong.
It is removed 0.5sec before the spell is cast and it only happens when you are under AF 3 or UI 3.
Test it by yourself, UI 1 and 2 are not removed before the spell hits, only UI 3 does. And that sucks for sure.
Why should our UI 3 be removed before the spell hits ? They could simply work harder and fix the double dip flare without this kind of amateurish fix.
Or at least do the same with Firestarter procs ?
