Dual Blades on Tanks? Does it need help? Would reordering the attacks help?

I'd slot it up more if I could, but other powers were more important, unfortunately. I did have a few more slots for it on my offensive build for Grey Pilgrim, so I only did it on the defensive build because I had to. No matter what, Tanks are going to find plenty of times where they'll use that Tier 1 power, so it's worth slotting it and using it if you can.
