No not at all, its a great last arc, however, it does attack at standard character waist level screen wide, so characters like the nekos are pretty much immune to it. same with Ciel's air knives, Mech-Hisui's air shotgun, etc. etc.
Haven't seen too many people, however, actually use last arcs...most of the time, they just burn the meter all the way down with health regen.
