Been doing Odin consistently since update and haven't seen any more or diff abjs than usual. I will say the drop rate in the normal chambers has increased substantially. We usually get at least 1 abj about 50% of the time now. Occasionally we will get double drops as well.
Additional note: unless they increase the number of max drops odin can give, adding sky drops would actually be a bad thing considering how easy they are to get (in comparison to some of the einherjar-only abjs). Double shura hands no thanks.
