Shooters are, IMO, useless. The RNG seems to hate them, as I've rarely seen MINE hit, and then, after not helping at all, they proceed to get killed by reinforcements, requiring my to use about six units to progress through a chapter instead of about twelve.
I also rarely field dancers, but, seeing as she can also fight, I probably will deploy and use her. For my playstyle and luck, Feena>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>Shooters
