I'm also have an idea for developer. What about ninja squad?
Default stats : Low defense but high agility
Weapon : Katana (Main Weapon) and Bow, Knife or Nunchaku (Optional Weapon)
Skill 1 : Increase agility.
Skill 2 : He/she can move after attacking enemy squad.
Skill 3 : Invisible for 1 turn. Cost 1 AP. He/she can move near enemy squads undetected. No counter attack from enemy squads if he/she decide to attack enemy squad.
