Here’s a list of current rewards and suggested changes. Most of them for things that have outdated rewards after normal.
Act I
Sister’s Burial
Current Reward - Bow Merc, all 3 Difficulties
Normal - Bow Merc
Nightmare - Rare Exceptional Body Armor, Revives Merc (if dead)
Hell - Rare Elite Body Armor, Revives Merc (if dead)
In all 3 difficulties I think it should be Leather, Hard Leather, or Studded Leather (and the appropriate varients).
Act III
Blade of the Old Religion
Current Reward - Iron Wolf Merc and a Ring (From Ormus)
Normal - Rare Normal Sword or Shield, Revives Merc (if dead)
Nightmare - Rare Exceptional Sword or Shield, Revives merc (if dead)
Hell - Rare Elite Sword or Shield, Revives merc (if dead)
Act V
Rescue at Mt. Arreat
Current Reward - Ral Ort Tal (All Difficulties)
Normal - Ral Ort Tal (Ancient’s Pledge)
Nightmare - Shael Eth (Rhyme)
Hell - Nef Lum (Smoke)
The goal of this one ^ is to make runewords that are appropriately useful for someone on their first playthrough. They are also runes that are relatively decent to find in those difficulties; but not exceptionally rare.
