I'm not even going to get started on Yama, WW, and Aizen (Aizen's subordinate did neutralize Yama in that arc afterall). But about your statement of the Zero squad losing their bankai... you do realize from this point forward Isshin, Kenpachi, Urahara, and the Zero squad are all going to be benchmarks for Ichigo.
