How often do you use S&B mode while not-blocking? (if ever?)

As I find my barb somehow end up with a lot of the gear for AC tank (TOD ring, epic Spec glove, +4 CHA tome, enough stuff to make a suite of red armor), I felt its a lot easier to TR xairs and build/gear up a new WF barb
The dilemma I’m facing is that I want to go THF when in full dps mode (ESOS strongly pull me towards that direction). So debating what should I craft the 4 insight AC on when in S&B mode?
If I never get to use S&B mode for attacking, then I might as well craft a healing amp/ healing amp/4AC dagger

It would also save me 2 feats (KPS and TWD), which I’m considering quickdraw and superior weapon focus (if I ever get tired of defender and decided to go Kensai)
