This is not the correct way to play destro. 15% crit chance is not that great of a damage increase to CB, especially compared to high end Int procs and DS.
The only times I would ever advise casting CB under the 4 set are:
-IF the gained embers from a SB execute proc the bonus
-if you just filled up your 4th ember
-if DS or any strong proc is also up
It's not a strong proc for CB on its own, and using it every time you gain it will certainly result in not having enough embers for better procs.
Instead, I'd recommend using Conflag (if you have one) during the proc in an attempt to fish for a 2 set proc, and then Immolate.
