I prefer to play as casters, and there are some things which I miss in WoTR as a caster.
Spirit Guide Oracle. Shaman wandering spirit mechanic is here, so, why not to add Spirit Guide archetype? It will be very benefical for caster oracles.
Shapeshift hex for Shamans (working with Master Shapeshifter to get limitless shapeshift):
Shapeshift (Su): The shaman transforms herself into another form for a number of minutes per day equal to her level, as alter self. This duration does not need to be consecutive, but must be spent in 1-minute increments. Changing form (including changing back) is a standard action that doesn’t provoke an attack of opportunity. At 8th level, this ability works as beast shape I. At 12th level, this ability works as beast shape II. At 16th level, this ability works as beast shape III. At 20th level, this ability works as beast shape IV.
- Extra Revelation feat for oracles (especially for Seekers and for newly introduced Spirit Guides).
