Before the recent patch we could easily solo Kil’Jaeden on mythic due to high dps but when I tried yesterday he would always jump to the next phase at around 50% HP and then spawn multiple Shadowsouls as well as Rupturing Singularity that after a few times has 2 in one corner one after the other with no chance to recover from the first one.
It seems now if you dps too fast he now does all the other phases are once overlapping, only way to kill him now was to slow dps until first phase change.
