Undead affected by disease?

[Alneyan]

Well, the Ring of Regeneration should also make further afflictions much less likely; have you seen this effect on diseased units PvK? (I never toyed with Regeneration and diseased commanders, so)

What I did see is high-HP Pretenders getting afflictions because of a disease much faster than they would if they only suffered 1 damage in battle (that, or there has been some tough luck involved, which cannot be excluded either).
