Can Healer LB2 raise everyone with weakness?

[Grimoire-M]

the problems with heal lb1 and lb2 is that healers can pretty easily get the entire party from 1 hp to full in a matter of seconds, so lb kinda has to be stringer that that at a minimum. i think if heal lb1 or lb2 was like pvp lb that instantly fully healed the party it would be worth it without heing too broken

One sure, two I think would be fine if it applied double weakness.
