If you're a SW you should try out this build ...

Playing since weeks with it and it's working perfectly, I don't even miss the Crushing Blow instead I am enjoying the Unstoppable talent and my healers like it too because of the shield I get upfront for several seconds. That's almost allways the time where you get the most dmg, so it also prevents getting aggro to fast for healers from scattered adds.
Regarding the free smash and the updated scream, you can leave it out if you lack some equip and go for the extra 4% dmg reduction of Dark Blood.
The problem with Kaon ... well, there you have no other choice but to cc the most annoying stuff, if not it might be not an easy job to keep them sticky.
