i have spica (aw maxed) , bashira cc-ed max , and nanaly aw 89. Adn that's bsides a max lvl aw monica and some other ranged units i can't remember now. I even wanted to cc the plat event archer which name i can't remember as well since i like her art quite a bit .

generally speaking , having archers is not bad. Problem is that they are expensive to cc. Also , having extra duelists is not bad either
