With all the changes since the release of Reaver's Reach, I feel it is time for an update of Dragontouched Crafting.
I am sure, at the time, it made sense to have "less than optimal" choices on some runes, but that time has passed.
My suggestion is to swap some runes for more useful ones:
Sovereign Runes-
Crippling: change to Shock (Sup. Magnetism VII)
Arcane Sigil: change to Acid (Sup. Corrosion VII)
Flame: change to Force (Sup. Impact VII)
Chill: change to Light (Sup. Brilliance VII)
Sound: change to Repair (Sup. ? VII)
Tempest-
Lesser Arcane Sigil: change to Efficient Metamagic- Maximize I or II
Spell Resistance 22: change to SR 28 or 30
Eldritch-
Lionheart: change to Fear Immunity
Improved False Life: change to Underwater Action
Striding: change to Freedom of Movement
There needs to be equivalent bonuses in the Sovereign tier for every Elemental type.
The usefulness of Arcane Sigils is limited, at best.
Enemies die too quickly for Crippling to be really useful.
SR 22 is outclassed by Drow and Monk SR 30.
Fear Immunity is much more useful than a Remove Fear proc.
Striding 20% and Imp. False Life are outclassed by other runes in the same tier.
