The types are too similar a bit with what they need to achieve.
Ranged is fine as is.
merge melee into direct combat and stealth.
Warrior and assassin basically.
Warrior gets shields or deflection akin to Karp fu, ability to charge at someone and deals a lot of direct damage. Can also break down walls.
Assassin can move trough walls and objects, is basically invisible, can attack from stealth/needs to be hit to be visible or maybe something else that uncovers it. Can also emag doors. Alternatively make it have greater autonomous range before it’s snapped back and unable to attack.
Mind control holopara would be a fun addition. It can possess a character for a short time, say a minute, and the process is similar to mindswap by changeling where the char spazzes on the floor for a bit. It would allow you to move a target to a more secluded area, have them pull attack a colleague or just let you into a department. Can happen either with memory loss or without it depends on how they wanna balance it.
Guardian/Healer that focuses on buffing and healing the user rather than straight up combat. Can grant it’s user an en energy shield mode, deflection from kinetics mode. Increased speed, meth effect, and maybe the wizards little magic wall that lasts a shorter time and doesn’t let the user pass trough it. Maybe also can absorb damage for user - all damage taken goes to holopara until it is dead and only then damages the user.
