I mean for real? nowadays, Shinigami are fightning opponents much above your every day hollow. Everywhere its BANKAI!!! BANKAI!!! BANKAI!!! i mean, in some of the arrancar Fights, they used their Shikai's for some time, But without Bankai their asses would be toast.It just seems as if once a Shinigami Reaches Bankai, it seems like their Shikai becomes incompitent.
