But generally, you may take your time with it, as training the rest of your team up to sniff will most likely give you more clearing power than Awakening one warrior.
what he said. just want to add one more point of Spica being a really good choice for AW asap because she makes crystal X much easier to clear. being able to do crystal X over crystal H means more DC in the long run. as for the rest, it's largely optional as variety might > a small pool of AW'd units.
