-Soulblights coming 2 seconds before new Fears go out almost all of P1, it kills people because there's only a .25 second chance to react to make sure people don't gain stacks of Fear. Losing someone in P1 is just a wipe, you can't afford to have someone dead that long it makes Rage/Fear harder in P3, it also isn't worth the brez because you need them in P3 for tanks.
-The random(which is more like 40/60) occasion where Fear/Rage go out a second after soulburst/bomb targets and burst targets someone with Rage. This one isn't so much instant wipe, but it causes deaths that shouldn't be happening in the first place. Rage targets can't be targeted by burst, but burst targets can be targeted by rage, that shit coding.
-Second set of Scythes basically happening within a half second of Rage/Fear target picks in P3 because of the random staggered cast from Sargeras.
You have a kill, yet you're that oblivious to how the fight works?
At the very least KJ was scripted, he was overtuned as fuck for a long time, but everything was predictable, the timers were accurate, and you could learn the fight like clockwork regardless of having a few people dead in the last phase.
