Mediocre Heroes

Many heroes are useless or have very limited usefulness. If you're just starting out, having any hero is better than no hero, but keep an eye out for heroes with a high rating in Appendix A. Focus on leveling up the highest rated heroes (being careful not to level them up too much). Once you have a handful of 4 or 5-star heroes, dismiss new lower-rated ones, and replace existing ones with new higher-rated heroes.
