And yet at the same time we've had fantastic Opifex Soldiers, Nanomage Enforcers, Atrox Doctors, Atrox Fixers, ... many of those combinations can contribute their breed strengths over to their profession, and almost every other combination in the game is just as strong as the others, with their breed strengths helping to cover weaknesses. Atrox Nano-Technician is pretty much alone in this, as all they contribute is a larger HP pool that still doesn't make much of a difference.
