My friend where have you been all this time! You seem to be forgetting that Rukia also went to the Soul Palace. And like Kirio Hikifune said. In the zero division things are taken to a whole new level. Way beyond that of anything available to the Gotei 13.

So it's quite natural that once she was able to at least move in Ichibei high density reishi atmosphere, that covered his palace, that that gave her a jump start to her powers development. Including of course the use of bankai.

And also don't forget that not only her control over her bankai was still weak and lacking. But her bankai is a double edge sword. It's is formidable in its destructive power, but it leaves her completely open to a counter attack, if it fails to kill her opponent. In fact all her opponent would have to do would be to shatter her into pieces. Seeing her entire body turns to ice.
