Empress summons before half HP.

Back when Empress first came out, and before all the hackers started in on her, the group I led in Khaini went with the strategy of trying not to touching Empress at all except for a few wacks. This worked fine for us for many many runs, and saved on wheels for the group. I think it was a patch in Nov. where GMS made it so she HAD to be damaged more than 50% before she would summon the 5 at once. That change and the influx of people hacking and driving down Empress Gear prices made it so it was not worth us going in and expending so many wheels.
