I'd rather follow up with Explosive Arrow... it may be a bit less damage but I don't have to stand in the middle of a bunch of very annoyed bad guys to do it. 
Cascade, level 50 Blaster (NRG/NRG since before it was cool)
Mechmeister, level 50 Bots / Traps MM

I do the same thing with my Arch/Fire blaster but use Fire sword circle.
Onibi---Fire/Fire/fire Blaster
I'm ready to burn it all.

ParadigmX City help the city.
So, with the new Alpha slots, I've found new joy in playing my Arch/MM blaster. And I know they are two seperate powers, but they hit at pretty much the same time, so...
Run in the middle of a group, fire off Aim/BU (while stealthed) trigger RoA and queue up PSW. Watch everything but bosses die.
With the ED diminished with the uncommon Spiritual Alpha slot, do it again 15 seconds later.
Awesome.
