That's true as well.

C/P something I wrote on another forum, if you had the same question about "what formation should I use":
When you are using a formation, you need to consider 4 things:
-The stats, obviously, but also...
-How vulnerable you are to AOE (Little spreadsheet about the vulnerability of each formation at the first turn of battle)
-How many units you can protect with one strong tank (for instance, Bison formation doesn't allow a tank to protect 2 others units behind him)
-And how well you can focus. It's related to the previous point, Bison can't use 3 characters to focus one unit.


Basically, I will go Crane, because I think the speed is extremly important (Enemies are usually faster, so it's like getting a free turn, much better any other stats), the vulnerability to aoe is the lowest with the python, and I can protect up to 2 units with my main tank.
