Made my Atlas a Mercenary. Even with his awful Spd growths, he'll still double 80% of enemies thanks to Merc base Spd, in turn making use of his high Atk. His Spd is otherwise really awful. Like, gets doubled by zombies awful. >.>
Atlas has awful speed growths? I don't know what your taking about. My Atlas currently has 21 speed which is the same has Saber and Kamui.
