I just did this fight last night, and what he is talking about is pretty much what happened for me. I just tunneled the emperor, interupting everything. I put T7 in dps stance and turned taunt off and he was killing the clones on his own before the next wave would come out. I ended the fight at 70% with T7 still alive, not having used ANY cooldowns.

I did this before and after the nerf (the trash is basically non-existent now compared to before), and the fight is noticeably easier. I geared out my T7 before and he died pretty quickly, whereas last night I went in with my T7 that I hadn't used or geared since I got Kira. What I found that worked remarkably well was to set T7 on dps stance, turn off taunt, and then just tunnel the emperor, interupting his casts. T7 handily killed all the clones, having one set dead by the time the next wave comes. Doing it this way, I ended the fight at 70% health without using any cooldowns, and T7 still alive.
