1 out of 20 times, the party wipes because you missed that crucial Shield Lob

As a healer I don't mind healing a low vitality tank, as long as those bugs and soldiers won't be hitting me.

Better secondary stats ensure those things won't be hitting you just as much as accuracy would. I've not once heard of a party wiping because a pld missed an attack. As a healer I do mind healing a low vitality tank as a low vitality tank can't survive certain things as well.
