Apparently missed the whole section where Kubo isn't doing that. I dont know why people assume any lieutenant or lower can be a captain. Kubo has detailed they are in their positions for a reason. It takes more then having bankai to be a captain. They have been specifically made to look weak in comparison to captains to showcase that they dont have what it takes regardless of bankai.
