The Stormwaker automaton head (in combination with the Stormwaker automaton frame) has not seen any new spells since the level cap was raised from 75 to 90. It's current spell repertoire is limited to level 75 still, and as such has become all but useless in the lvl 90 game environment. Giving it access to Cure V, Stone IV, Water IV, Aero IV, Fire IV and Blizzard IV would do a lot to bring this automaton up to date. Given the Red Mage casting similarities of this automaton head, Refresh and Dispel would also be supportive to definiting it's role further.

The Soulsoother head (white turban) is superior in healing spells while lacking elemental damage spells, but it's healing role is crippled by enfeebling effects of any kind on the automaton and master. The Spiritreaver head (black turban) has superior elemental damage spells, but is unable to heal the master, itself or party members. The Stormwaker head (red turban), with above mentioned spells added, should fill the gap between the two other heads.

Another automaton frame and head that has fallen into complete disuse is the initial automaton: the Harlequin. It's lacking any noticable distinction from the other frames and heads, and serves little more purpose then occupying a spot in the automaton equipment window.
