It's been some time since we had these battles, just a nice way of giving orbs for defeating foes that have crazy investment. Especially the Dragon Squad, that team caused a lot of pain and I didn't touch that battle at all. I really would like new battles and the returning battles instead of just throwing the returning battles at us as some player stats have completed all the maps and expect new Challenges.
Will there be seasonal units with high investment? Teams that are themed? Another Dragon Squad with M!Grima and S!Y!Tiki? What does everyone about this if they return?
I don't mind them, in fact I welcome them.. Well, except the dragon team. The other teams had some type of thought to them, like the one that had effectiveness to cavaliers with three wolf tomes and one Zanbato. I liked those ones.
The dragon team was just classic Dragon Emblem and was extremely boring to fight against, so I hope that one doesn't come back.
Man, I would love a return of this. My favorite team was the one titled "Four Beautiful Men"--or something along those lines--and it featured the four units that were drawn by Yamada Akihiro: Ogma, Gunter, Jaegan, and Zephiel. (It helps that he is also one of my favorite artists in FEH, even though others may say this his style doesn't really "fit" the game.)
