In the Federation, affinities were never given much weight. Everyone knew the tiers ranged from I to VII, but it hardly mattered, most trial takers never awakened an affinity at all, and those who did usually ended up with something weak and unimpressive. The situation was so poor that across the entire Federation, only a handful of people had ever reached Tier III.
It wasn't hard to understand why. Affinity could only be awakened after breaking into C-rank, and unlike other stats, it was fixed. Once awakened, its power could never be raised through effort or training. Because of this, information was scarce, and interest even scarcer.
