Thank you for that. Your build does look better (twice the regen, a lot more smashing/lethal res, haste) and a lot easier to complete. Mine has 60% more damage, but with close to twice as much haste on your build I'm guessing it almost evens out.
I don't play blasters much, so I'm not even completely positive what to focus on. Seems to be haste, regen, ranged defense, and the obvious damage.
I used your build and modified it a bit. Is there a reason you placed a lot of different Chances on the same power like on Ice Arrow?
