Is there any ranking as to the usefulness or rarity of some of the offered quest rewards? Yes, I know that its possible to just run through the content multiple times and get all of them - but I don't want to do that yet, my furthest char is Act 2 Normal ;)
What considerations should I think of, for e.g. when choosing between
Added Lightning Damage and
Weapon Elemental Damage for a Templar? Are there general 'rules of thumb' to keep in mind?
