Sisters when Kings Fall was the current raid was a total pain, almost impossible with groups of randoms. Many groups would disintegrate at that point on Normal, and on Hard you could be there for hours, hoping eventually RNG chose two competent, fast jumpers who could get round because even with that you would only just have time to kill them both before being annihilated. And defeating Oryx on Hard took people many many hours of repeated wipes from just one mistake each cycle... Both of these encounters were too unforgiving of a single mistake. So Kings Fall was a raid of continual wipes and start the cycle again. Now it is very easy with the massive light level advantages. I used to hate it but was determined to defeat it and did it on Hard, all 3 chars all challenges and every fragment for MoT Y2.. Now it is the raid I have played the most, and I probably prefer it to WoTM and miss the challenge!
