I'll probably keep Blindin Flash unless they buff LTK or SSS to Barb skill levels.
As you know there is a LTK rune(Skorpion Sting) that removes the KB and replaces it w/ a stun. It could very easily take BF's role as a CC.
SSS even at 1777% weapon DMG and i-frames still isn't worth the 30 second kool down. A simple kool down reduction on SSS would deff make it more attractive.
