Another thought:

You know how in previous TES games if you got slapped by a bear or bitten by a wolf you could sometimes catch stiff-joints or brain-rot?

Will ESO have this feature? Will there be a chance at catching a disease when fighting wild animals or some other sort of particular nasty?
Has an MMO ever done anything like that?
And what will you need to cure it? Just a cure disease potion or visit a shrine or doctor?
Will Argonians or Bosmer be immune or at least resistant?

Or will ZoS just see this to be an inconvenience and just leave it out altogether because "Its not fun and not in the meta of an mmo." I personally think they should have it. If you could fight wild tigers or bears in your spare time, you could be prone to catching some illness from a large claw to the face, and let me tell you, a healing potion isn't gonna stop those viruses.

Thoughts?
