There isn't much to question when it comes to SCH attribute points

All MND unless you have a specific reason for not doing so; reset your stats with the very inexpensive Keeper's Hymn if you play SMN as well.

INT is a complete waste for SCH; VIT is wasteful unless you need X HP to survive a specific raid attack and don't have the gear to reach it (not really a thing now with our level of gear + Echo); PIE is wasteful since you don't need all that much and have tons of it available on healer gear.
