5 skill ranks for something that restores 10 FP with a very specific weapon type (a tome), on a class that can be tight on SP management. This is for the most part not something you would want to pick, even with leftovers, because of its lackluster effect. 

Can it be changed to either be like:

According to Plan

(Fluff Text). If you have a Tome equipped, and every time an enemy is defeated, you gain 'According to Plan', which makes your next Tactical Order skill or Tactical Formation skill gain a bonus effect, cost no momentum and FP, and restore FP based on Rank.

Rank 1: 3 FP
Rank 2: 5 FP
Rank 3: 10 FP

Order effects are only active as you trigger their initial condition.
Assault Order EX - Increases Critical Damage by the same amount of the damage boost.
Cast Order EX - Increases Hit by the same amount of the damage boost.
Guard Order EX - Guard effect becomes Swift Guard instead, and cannot be Guard Broken.
Charge Order EX - Movement does not trigger any field effects or field objects.

Formation effects are only active while you're standing on them.
Attack Formation EX - Reduces the momentum cost of Melee basic attacks and offensive skills by 1M. Immunity to Knockdown.
Bunker Formation EX - Immunity to Guard Break, knockback and pull effects.
Volley Formation EX - Increases the size of basic attacks from Ranged weapons (4 range circle).
