Eh, increasing the chances of dealing 150% damage without needing a weak point is far from garbage. With all the Knights that have some form of increased crit rate for at least 4 squad members these days (Pineapple, Lupine, Easter Balloon Vine, either version of Mei Plumblossom, Cactus, Aizoon Stonecrop, etc) it's not too hard to build up a solid crit chance.
