Shifter's Change Appearance can ditch the Friends cantrip in morpho-social situations.
Kalashtar Druid loves the telepathy for Wildshape
Dual Mind is fab for any defenses first build.
Shifter Wildhunt Mark The Scent = a just get me close for a tag, then retreat, lick wounds, power up, go get it.
Warforged Wizards are very happy with the AC.
Sorlock chez is now corner case re-incarnated (obligatory don't do this to homegame warning yawn).
