Sinestra unplayable :
Twilight Slicer https://www.wowhead.com/spell=92852/twilight-slicer
27000 to 33000 Shadow damage every 0.5 sec in a 5 yard radius
[feels like it goes through the whole room]

Twilight Essence https://www.wowhead.com/spell=88146/twilight-essence
Twilight Essence has the same problem as with the orbs, not only hits in the area but also feels like it goes over the entire area

Ala'kir doesn't use his heroic ability Lightning Strike or move, even though I disabled it in SQL (it doesn't work in normal but HC)

Atramedes
Sonar Pulses spawn on players, but they should spawn in the boss's hitbox and fly to their targets.
