TP rotations aren't a thing.. Nutaku hate us aha. So either awaken or Saki. Saki is needed if you wanna do dwarfs n giants for black fairy's. She has her uses but fairly niche. I would say awaken units as for needing 3 ha. While it's not 100% needed some maps may require it or some different strategy for 2 ha. Spica, iris are very good awakens idk Sasha or sybillas
