When Lucky Dance is active with no other modifiers, the in-game tooltip on Banana Barrage is showing 100% to hit.

Yet I miss roughly 50% of the time. I did a forum search but couldn't find anything to explain it. Is it only the 1st hit/application/tick of Banana Barrage that is guaranteed to be 100% ?

Also, what's the baseline crit chance percentage of any 'normal' attack ?

It used to be all hits (usually coupled with the Moth attack), but that got nerfed back in MoP to only the first hit getting credit.
