I was the CO of Medstaff, and I created it mainly when working on the Jania map (before we lost it), so I've used that medbay a shit ton.
It is small, but you can easily deal with it. You do not need 1500 different rooms for roleplay. Hell, there are rarely more than 2-3 patients at a time unless you are doing a scheduled checkup.
That room is multi-purpose. Depending on what you need, it can be either a ICU, a RnD lab, Quarantine, and so much more.
RP does not need a ton of rooms and textscreens everywhere. You can do that in your head.
That Medbay works fine. The medical staff made it work just fine, so can you.
(so this will be a big -1)
