New fractal boss fight stucked at 5%

[EpheSOSIayer.6370]

Hi,

I did the new fractal yesterday the first time. At 5% HP of the endboss, you have a last "splitphase" with a timer. When the timer is over and the priest you have to kill is nearly dead it is possible that the priest dies on condition. This leads to an endless loop, bringing the boss to 5%, CC her, entering the spilt phase where you can't do ANYTHING until the timer is over, etc.

Please fix this, it was our 1st run and it was really disappointing that we have to /gg the whole fight.
