Soboro can attack 1-3 times, each with equal chance of happening (Is this correct?). If I DA on any attack round it would automatically limit my attacks to 2 for that round. Since 2 attacks is going to be the mean for the number of attacks per round, using the Brutal Earring isn't going to hurt my over all mean, it will just increase the number of median attack rounds. Since, statistically, the number of 1 attack and 3 attack rounds should still balance (because DA should, statically, proc equally over all three possible attack rounds) doesn't that mean that the Brutal Earring essentially becomes a wasted slot?
