as much as i really do agree that it shouldnt just one hit a person at all. there are ways to counter it.

Attunement, Sacred Prism, Cover, Tank LB, Stun, tank immunitys, swift cast shields, Manawall, testudo, carnal chill, thrill of war. as well as any effect with sleep knock back stun etc if fetterward isnt up. which can be used to somewhat stop it. but again, its very limited situation use. some classes like summoner literally have nothing to defend against lb.

As a healer, ive noticed without 2 tank accessorys i WILL die in one shot it if dont have one of the above options available to me. being as lb is nearly all ways paired with stun and fetterward it falls into the realm of team work. which single cue doesnt exactly help with. id like to see it do about 7000 capped damage. 75% damage on target. a flat out kill is just silly.
