Well for exp fodder seems not giving much exp for shiho and I already max CR/SU my main Shiho. So maybe I will save it for Rainbow Crystal later.

DMM Side:
Oh so battle mage can be used as tank too maybe then I will try to upgrade her and her aff increase hp and def quite good for tank.
So Ranger is useless, then I will stick at archers for my physical ranged. About Druid, maybe better to search some videos to how to use her. Cause I also a bit confused how to use her when the tree of life token taken 1 slot unit and exchange it for healer with range lower than healer which makes me a bit confused how to use it. On the bright side, then I will also upgrade bandit and yuyu then for main team.

Thank you for the advice lolix and soranokira
