Oh my. Not a smart move to sacrifice the bankai of FOUR captains when all you needed was a single test case, and in the middle of an invasion at that.

One potential weakness of the Quincy bankai-stealing ability is that its been used every time a bankai has been released in their presence. The Captains should of thought about releasing bankai before they come anywhere near the battlefield. Plus it makes the stealing ability still a threat without being overpowered. Ambushes can be scary if your an unprepared captain.
