This would be a great Cyrodiil-only mechanic to encourage people to spread out...
Though personally I hope every zergball comes down with a case of the ol' Black Heart Blight!
Really we do it without like, the musical instruments. This is the only musical: the mouth. And hopefully the brain attached to the mouth. Right? The brain, more important than the mouth, is the brain. The brain is much more important.
Wow, this post got rather necro'd. But I'm kinda glad it did, it's a pretty nifty idea. Though there's an awful lot of cure abilities, so wonder just how readily they can be purged...
Reminds me of a long-ago time in Daggerfall. The game, not the city in ESO. Finished a dungeon/quest, got out, saved, quick-traveled to a city. A screen flood of "You feel somewhat bad" and I died at the gates. A couple retries and WTF moments later -- because no diseases were showing on my character sheet -- I just plain walked the WHOLE way to the city, arrived in the middle of the night, climbed the wall, hurt myself getting back down, and went to a temple to get cured of an invisible disease (guess it was still incubating).
I kinda miss moments like that. Especially climbing.
