Also, the power ranking is based only on squad set 1. Depending on how tweak your set 1, the power ranking can change very easily. Personally though, I don't care for the power ranking, since this is not a competitive game, and some rng is involved in getting the correct type & level Manyus for whatever unit you need. Or in some cases, someone pulled a new character he really likes, and is currently slowly getting it strong enough to fit into one of his squads. Either way, it isn't really an accurate way of representing even progression.
Huh, interesting, never knew about that. Still, doesn't really affect anything in my opinion.
