You can make the exact same argument about surgery. not all doctors know surgery, but they still have access.
Why?
Because what a person can do is decided by their character's skills, not the job they've chosen. Characters can hold multiple degrees if they're old enough, and be skilled in multiple fields. Especially skrell. And IPCs
Not all doctors will be skilled in virology, but some definitely will be. Those that don't have the skills will stay out, they generally do anyway, i've never observed any problem with tons of inexperienced noobs crowding into virology. I don't think there's any problem here that needs to be solved except crate access.
If people are abusing extra access too much, admins can step in, and they will, they already do. I got bwoinked about doing surgery and chemistry as a nurse, and stopped when admins made it clear about what IC skills are reasonable (I resumed surgery after promoting to doctor a couple weeks later, with specific admin approval)
Let RP decide the restriction, not mechanics. Admins will deal with abuse.
Giving medical doctors access to open the virus crates is sufficient, it will change nothing in terms of balance (doctors can already take virus samples from virology) but it will be a quality of life improvement for virologists. Everyone wins, no farther-reaching changes are needed.
That's refreshingly self aware. My main concern was the old "I'M A NURSE NOW BUT TRAINED IN ALL FIELDS!!!111" which is a pet peeve of mine. Such things should only really apply to a skrell/Diona imo since that's their species/race benefit. No Human/Unathi/Tarj paramedic/doctor/chemist/virologists pls, it's lame. BUT I DIGRESS.
I agree with you Nanako you diamond. Make the crates all access.
