Well yeah, they are random, but the radius of damage is only 8 yards and you have time to move out of it. Literally everyones focus should be staying alive then DPS after. For healers you can move a bit then heal. Even on mythic I can take 2-3 hits before I die, so the damage isn't super unforgiving.
Oh my bad then. Still tele is godly.
That's for all lock specs right?
