But! They infringe so much upon RP. The gnarly ones typically end in death if you don't get them treated. The other ones aren't particularly infectious.
I would love to see more viruses that are less deadly and less vicious, but still disable the characters somewhat. I'm unfamiliar with coding possibilities, but a stat drain to a certain floor would be great. Something that makes life obnoxious, but not completely restricting RP. There could be some that occur more often even in topside circles too.
It bums me out that there's not more topside and the RP there is typically reserved for Red. Maybe the cures could take time rather than be instant fixes?
It's possible other players wouldn't be interested in this - but I thought I'd give my suggestion :)
