Asides from plasmaman having a free space suit, they cant wear anything else like a helmet or exosuit unless its fireproofed and their suit too, doing so is a risk cause itll set people around on fire, plasmaman ALSO gets more damage with brute or lasers, they got a bigger chance of bone broke as far as i remember.
I believe every race already has a decent weakness.
Vox can die to EMP and have weak bones(higher chance of bone break) (They're loud and can be located way easier too when speaking)
Kidan cant even wear glasses, its annoying i believe they should be allowed to get special goggles. and pest spray kills them
Diona gets killed by plant b gone, they're strong but SLOW, they can self regen
Slimes, alot of stuff, cold, temperature gun, frost oil. Able to grow their own limbs.
Greys, fire extinguishers, and gets more damage, water kills them. Psionic Communication
Drasks, heat kills them, so does a temp gun. Breathing cold oxygen regenerates them (also loud)
IPC's, EMP of course. Easily repairable
Skrell, no idea but inmune to water like /the pool/, cant drown
Unathi no idea what's bad in them but they have claws and i swear i dont like the claw decap chance
Vulps, no idea. claws
Tajarans, no idea neither. and claws
Humans, bigger knockdown chance.
MY ACTUAL SUGGESTION
I suggest kidans can spawn with special goggles for them like sec huds , its impossible to play security as a kidan specially when you get flash gear, and you have no protection of it.
Raise the chance of greys extinguishing fire when they roll, litterally when theyre set on fire, theyll obviously get fire extinguished(with a intent of helping).. and thats going to kill them.
Plasmaman should atleast come out cloned but in a critical state, it's not fair to instantly take a player out once cloned then having no DOCTORS knowing how to revive. Atleast giving a chance to the doctor to put them on a cryotube before they die, seem fair.
One more suggestion even though the race isnt mentioned REMOVE CLAW DECAP CHANCE
