Advice on this Commando Retaliation Build?

I saw other Commando retaliation builds, but I wanted to try something a bit different and would appreciate advice if this build would be viable for ultimate before starting the game. The idea of the build is to proc as much retaliation via counter strike and blast shield as well as proc as much “on attack”, “when attacked” and “when shield block” skills as I can find. I feel like perhaps my damage is too split to be viable, but I’d like to see if this is viable anyways.
