I've never paid attention to the boss notifications, bar the ones that would tell me when she would potential lock, so I didn't know about that particular message.
Pre-Unleashed, I had always used the aggro-system to my advantage when duoing on my Phantom with a Kaiser, and it never failed me. We'd keep the aggro on the Kaiser since Giga Wave attacks (...faster?) than Mille Aiguilles, so we would only have to keep track of one DR timing. [For some reason, using Rapid Fire always switched the aggro onto me, so I guess the rankings are determined by hits-per-second, not damage-per-second, as said above?]
Yes, the aggro-system tends to become unreliable for timing DR with a greater number of attackers. But its core function to rank hit-rates in descending order has always worked properly in my own experience, and incidentally, I found it to be very reliable for duoing.
