I think that teqnique would work great for my rage builder abilities as a SW. So if I press 1, 1 and 2 get sent to the game window, and I would put my Sundering Assault and the other rage builder in quickslot 1 and 2. Since Sundering assault has a few second CD it hopefully would be used when it was off CD. Not sure if it would work since I haven't tried yet since I am unsure of the legality of it. Also great for an "Oh shit" button to blow all defensive cooldowns.

I'm an old man, so my reflexes ain't what they used to be, so any help I can get legally to perform better is ok in my book. If it's not legal I won't fret over loosing out on a CD 30% of the time. I can live with that.
