I have this option... and I'm really trying to figure out why this isn't an absolute no-brainer.
In the Shaman corner:
Chainmail armor
+3 power at -1 focus over druid
Nature spells, augmentation spells, and Blight spells to boot!
Slightly more weapon choice
Stat leaches instead of stat buffs
In the Druid corner:
We get Cloak of thorns
So what am I missing here?
