Thanks again for the feedback.
Trying a different format on for size, this one emphasizing troop role, rather than rarity (for now I’ll maintain the original list as well). I also included the lower-rarity faction troops (marked by “*”), which serve similar functions as these troops in general, and you’ll want to consider while building teams. Some troops straddled the classifications I came up; happy to revisit their placement if you think I got it wrong.
