Burst is good. That's why your opener sucks, it has no burst whatsoever, it's just plain bad. And fyi, 30k initial burst in a raid is horrible for an SP with avg iLvl 376 (didnt bother to armory you, but that's what you said). Also, applying Dots after Archangel is bad since you don't have the 10% extra dmg from Evangelism. VT > SW:P > DP > MB > SF > MF until MB comes of CD again (in which case u obviously MB) > VT and DP > Archangel, beats your opener hard when it comes to burst, and is less RNG dependant. But yeah, your loss if you want to do it your way.
