Post here a list of characters that don't get all the attention but are hidden gems:
Assassin undead axis gunner- power move steal beneficial effects, alternative to wikerdog king
Assassin Death dog-power move charges all allies damage! Stronger than typical boost. passive ability like blue bats
(All) Newborn of lights- with among highest atk or magic stats, +single enemy attack, most effective in LoL boss when you have affinity over the element. AoE characters are nice but is comparable to a slash when you need a hard stab in LoL/boss type fights
Edit: meant undead axis gunner, not soldier
