Feathers Unsullied

One allowance here buys 1,207 gil, the best on the Lv 52 battlecraft rung — matched exactly by 1 other leve of the 6 there, with the rest trailing at 1,009 gil or less.

Across that rung the return runs from 550 gil to 1,207 gil per allowance — 5 distinct figures spanning 119%, so the wrong pick leaves 657 gil of the allowance unspent.

On whether to wait: the best Lv 54 battlecraft leve returns 1,332 gil per allowance, 10% more than the best on this rung, while the Lv 50 rung behind tops out at 839 gil.

At Lv 52 this data holds 72 leves paying gil across 3 categories: the 6 Battlecraft ones average 895 gil per allowance, the 18 Fieldcraft ones 694 gil and the 48 Tradecraft ones 459 gil, which puts this leve 35% above its own category's average.
