The disease thing seems more in theme with Shartak. We need more stuff which would make us all die.
Maybe make newbies immune to diseases for a certain time period although. Last thing you need in a new game is to have "Day 1: Caught the black plague today. Turns out I lose half my HP every hour! I'm so

ed"
Yeah, time period rather than level would be good, since i'd hope the suggestion would trip up a lot of the low-level farmer alts.
On that note a
contagious disease would be fantastic, especially if there was some specific thing that triggered it, instead of just being in the same square with someone or talking.
That would be cool! Like an out of date First Aid Kit or faulty herbs causing disease!
