Should I re-cube my Empress Overall?

The chances of most shadowers getting hit twice within 3 seconds without iframes are tiny, I only have ~3.3k avoid and it rarely happens to me. If you look at the numbers for attack speed, and assuming you're invincible for the duration of bstep's delay, you get between 900 and 1120 ms of vulnerability within 3 seconds of being hit while using bstep+SB depending on when u get hit, effectively making the potential line only half as effective as it is for most other classes even before you include shadower's high avoid and shifter. Also, for the occasional super-KB attack, you can't move for an extra 2 seconds (personally, I'd only use that potential on classes with stance effects not including infinity just because of this).

tl;dr; 1st line is close to worthless on a shadower.
