I just promoted my first BO to LT. and am trying to figure out what skill to give her. She has High Yield Torp 1 and Focus Fire 1. I gave her High Yield Torp 2 and Focus Fire 2 as her skills but I'm wondering if I'm being too redundant by doing this. Should I pick somethin g else like Rapid Fire Cannons or something? Am I being too specialized here?
