TURN UNTHREAD
But seriously, during the playtest, I brought this up. I lobbied for a Wis-focused and a Cha-focused archetype for the Tactician (a la Sage), and it remains a possibility.
For those who haven't preordered Psionics Expanded, there's some very nice material in the latest releases for the Tactician; the Battle Medic archetype in particular is pretty sweet for those hoping to do a support-Tactician.
