[Star Wars] During the Clone Wars, what was the most underutilized and underestimated vehicle that could have been vital for many victories if used properly?

Or if there is none, what's the opposite situation? A vehicle that was continuously used improperly with no regard for it's actual ineffectiveness?

CIS Boarding craft were all used incorrectly.

If you are capable of delivering hordes of Super Battle Droids into the interior of a target capital ship (and past the shields at that), you are equally capable of delivering a warhead that could do much more damage than those droids could.

EDIT: Also, if you are dead-set on delivering droids to the target (because you want to disable or capture rather than destroy) then Buzzdroids would be a much better tool for the job, and would be much harder for the crew to deal with as they could get into critical spaces inaccessible to the clones.
