Remove pathology until it's balanced.

I knew I was missing something from my post, and that's exactly it! I hadn't thought of the whole "temporary cures" part of it, I love it. I think it'd also slot well into "rollback, then reintroduce as appropriate" since it would give people a much smaller pool of symptoms to become at least passingly familiar with the cures for. "Memorizing" a bunch of "If I notice X symptom, do Y" is, imo, actually good because it's not really rote memorization but rather association, and as long as the associations make sense, that's a fun "aha!" to figure out.

Later tiers can not only be more threatening, but require supplies that can run out - as you say, supplies of a medicine running out is another vector of attack an antag virologist could use. It'd be much more interactive and have more counterplay than the current system, at any rate.

I consider the addition of more suppressor to be part of Part 2 - making virology more accessible. Not only using it but, arguably more importantly, countering it.
