Someone proposed to make the Caster LB a Single target LB, I know it would fix a lot of problem, but I feel like caster won't do their work :/
Other than make its cast time a little longer I hope they wont balance his power, something like "The center of the AoE deal the maximum damage, more far the target is and less damage he will receive",
so you won't zerg an etire party and after even a weak hit you will be unbound/awake.
