Dusting off my old WM/SD build, I took some newer lessons I've learned, the latest SD build I could find here, put something together, and gave it a test try on some Council in Brainstorm.
In the words of the man: Good Gawd Awmighty.
So, apparently putting the Critical Strikes proc in Shatter, and leading both my AoE and ST rotations with it, turned her into a one hero wrecking crew. I had never seen that many 'CRITICAL' pop-ups at one time. And the proc and criticals pop up more on ST than it does on my DM/WP. Spawns were clearing at near-team like speeds and even the bosses didn't take long to wear down. I even managed to make end use manageable, and the only real issue is with runners that survive the initial onslaught and taunt aura. Other than that, wow. She was putting my tanks and brutes to shame.
Posting the build here to share and in case I'm missing anything, but I'm pretty happy with the results I've seen so far.
